Troops are one of the main foundations of your army in Last War: Survival.
Heroes provide abilities, skills, and combat bonuses, but troops determine how much of your squad's potential can actually be used in battle.
A strong account therefore needs more than powerful Heroes. You need:
- High-tier troops
- Enough troop quantity
- Strong troop Research
- Efficient Barracks
- Proper troop training and promotion
- Smart speedup management
- Correct event timing
- A strong match between Heroes and troop type
The goal is not simply to train more troops. The goal is to build the right troops efficiently and spend your training resources when they create the most value.
How Troop Development Works
Troop development is affected by several systems:
- Troop tier
- Troop quantity
- Barracks level
- Training capacity
- Training speed
- Troop Research
- Hero development
- Troop-type bonuses
- Account progression
- Events and temporary bonuses
A higher troop tier provides stronger individual units, while a larger army allows your squads to use more of their available march capacity.
The strongest accounts develop both quality and quantity.
Troop Tiers
Troops are divided into tiers, commonly shown as T1, T2, T3, and so on.
Higher tiers provide stronger troops and greater combat contribution.
The standard Barracks progression is:
| Barracks Level | Maximum Troop Tier | |---:|:---:| | 1 | T1 | | 2 | T2 | | 6 | T3 | | 10 | T4 | | 14 | T5 | | 17 | T6 | | 20 | T7 | | 24 | T8 | | 27 | T9 | | 30 | T10 |
These thresholds are the key levels to remember when planning Barracks upgrades.
A Barracks does not need to be upgraded one level at a time solely for troop progression. When the goal is to unlock the next troop tier, the important milestones are the tier thresholds above.
Current troop references confirm the T1–T10 Barracks progression and that T10 requires a level 30 Barracks plus the relevant Research requirements. citeturn1search0turn1search4
T10 Troops
T10 is one of the major troop progression milestones.
Unlocking T10 requires more than simply reaching Barracks 30.
You also need the appropriate Research progression in the Special Forces path.
This makes T10 a major long-term investment involving:
- Barracks progression
- Tech Center progression
- Research resources
- Valor Badges
- Large amounts of normal resources
- Time and speedups
Once T10 is available, your account should normally prioritize building a strong T10 army rather than continuing to invest heavily in lower-tier combat troops.
T11 Troops
T11 is an advanced troop progression system introduced after the later seasonal progression.
Current game references indicate that T11 progression involves the Armament Institute, Armament Research, and additional resources, with Barracks 35 required for T11 training. citeturn0search2
The exact T11 requirements and available systems can depend on your server/season progression.
The important principle is:
Do not treat T11 as simply "T10 + one Barracks level." It is a separate advanced progression path.
T11 progression can involve:
- Armament Institute
- Armament Materials
- Armament Cores
- Advanced Research
- Restricted Area Training
- Barracks 35
- Large resource requirements
Because later-game systems can change with updates and seasons, always use your current in-game Armament Institute and Barracks requirements as the final authority.
Barracks
Barracks are the main buildings used to train and promote troops.
Barracks level affects:
- Maximum troop tier available
- Training capacity
- Troop development
- Promotion options
- Long-term training efficiency
Higher Barracks levels therefore provide both immediate and strategic value.
Barracks Upgrade Priority
Do not automatically upgrade every Barracks equally.
Your Barracks should be developed according to your troop strategy.
A useful priority is:
- Main/highest-tier Barracks
- Barracks needed to unlock the next promotion tier
- Additional Barracks for training capacity
- Lower Barracks used for a waterfall/promotion chain
- Remaining Barracks
The reason is simple:
Equal Barracks levels can actually be worse for event optimization than deliberately staggered Barracks levels.
Extra Barracks
Additional Barracks can be unlocked through Research.
Extra Barracks are valuable because they provide:
- More simultaneous training
- More total troop production
- More promotion steps for waterfall training
- More flexibility during events
- Greater recovery speed after combat losses
Researching Extra Barracks is therefore an important long-term development goal.
Current research references identify Extra Barracks as a major Development-tree milestone. citeturn1search13
Training Capacity
Each Barracks has a maximum number of troops it can train in one batch.
Increasing training capacity allows you to produce more troops per training cycle.
This matters because higher training capacity can improve:
- Daily troop production
- Event scoring
- Waterfall preparation
- Recovery after PvP
- Speedup efficiency
A larger training batch also means fewer individual training cycles are needed.
Training Speed
Training speed determines how quickly a Barracks completes its current training queue.
Training speed can be improved through different account systems and temporary bonuses.
Possible sources include:
- Research
- Survivors
- VIP
- Alliance bonuses
- Events
- Other account buffs
The exact available bonuses depend on your current account and game progression.
⭐ Survivor Optimization for Troop Training
Survivors can be extremely valuable when preparing large troop-training batches.
Some Survivor skills can improve areas such as:
- Training capacity
- Training speed
- Resource efficiency
- Other military-development bonuses
Before starting a large training batch, check the Survivors assigned to the Barracks.
Training Capacity Optimization
If your Survivors can increase the number of troops trained in a single batch, assign the best relevant Survivors before starting the training.
A practical sequence is:
Check Barracks
↓
Open Survivor Assignment
↓
Equip the best Training Capacity / Training bonuses
↓
Start the training batch
↓
After training starts, adjust Survivors if needed
The important detail is that the training batch uses the Barracks' effective capacity when the training is started.
Current game references specifically document using Survivors to increase the training cap before starting a batch. citeturn1search1
Always check your current Survivor skills before a large training session. A small capacity increase multiplied across many training cycles can create a significant difference.
Training Speed vs Training Capacity
These two bonuses are not the same.
Training Speed
Reduces the time required to complete training.
Training Capacity
Allows more troops to be trained in one batch.
Both are useful, but they solve different problems.
For event preparation, training capacity can be especially useful because it lets you create larger batches of troops before the event.
Troop Quantity
Having high-tier troops is only half of the equation.
Your army also needs enough troops to fill your marches.
A powerful Hero lineup with an incomplete army will not perform at its full potential.
A healthy account should maintain:
- Strong main-squad troops
- Enough reserve troops
- Adequate Hospital capacity
- Enough troops for additional squads
- Enough replacement troops after PvP losses
Troop Types
Last War has three primary troop types:
- Tank
- Aircraft
- Missile
Each type has its own combat strengths and weaknesses.
The basic counter relationship is:
Tank
↓ counters
Missile
Missile
↓ counters
Aircraft
Aircraft
↓ counters
Tank
Current combat references describe the same triangle and its importance in PvP. citeturn0search4turn0search8
Tank Troops
Tank formations are associated with durability and frontline combat.
They are commonly used when:
- Survivability is important.
- You want to absorb damage.
- Your Hero lineup is built around Tank Heroes.
Tank does not mean that every Tank squad is automatically defensive.
The actual performance depends on:
- Heroes
- Skills
- Equipment
- Research
- Formation
- Troop tier
- Enemy matchup
Aircraft Troops
Aircraft formations are commonly associated with offensive pressure and are strong against Tank formations.
They are useful when:
- Your main Heroes are Aircraft.
- You need strong offensive pressure.
- You are targeting Tank opponents in PvP.
Missile Troops
Missile formations are commonly associated with ranged/offensive damage and counter Aircraft formations.
They are useful when:
- Your main Heroes are Missile.
- You want strong damage potential.
- You are targeting Aircraft opponents in PvP.
Troop Type and Hero Synergy
Your troops should match the Hero composition of the squad.
For example:
Tank Heroes
↓
Tank Troops
Aircraft Heroes
↓
Aircraft Troops
Missile Heroes
↓
Missile Troops
Avoid building a powerful Hero squad around one troop type and then using an unrelated troop type without a specific reason.
Your:
- Heroes
- Troops
- Formation
- Equipment
- Research
- Drone
should work toward the same combat strategy.
Troop Type Counters
The counter system matters most in PvP.
A type advantage can significantly change the result of a battle between otherwise similar squads.
Use the basic triangle:
Aircraft → Tank
Tank → Missile
Missile → Aircraft
When scouting an opponent, identify their main troop type before deciding which squad to use.
Do not rely on Power alone.
Training Troops
Training should normally remain active.
An idle Barracks means lost production time.
Good habits include:
- Start a new training batch when the previous one finishes.
- Use available training capacity efficiently.
- Keep your Barracks active when you are online.
- Start longer training batches before leaving the game.
- Prepare low-tier troops when using a waterfall strategy.
What Should You Train?
The answer depends on your account stage.
Before High Tiers
Train the highest practical troop tier while continuing to work toward the next unlock.
Once a Waterfall Strategy Is Available
Train a lower tier during the week and promote those troops during the appropriate event.
After T10
Your long-term goal should generally be a strong T10 army unless you are actively progressing toward T11.
During Heavy PvP
Prioritize recovering enough high-tier troops to restore your main marches.
Troop Promotion
A Barracks can promote lower-tier troops directly to the highest tier that Barracks can currently train.
For example:
T5 → T8
can be performed in a Barracks capable of training T8.
You do not have to manually upgrade the same troop through every intermediate tier when simply trying to create a high-tier troop.
However, this creates an important event optimization opportunity.
⭐ Waterfall Training
Waterfall Training is one of the most important troop-development strategies for players who care about Alliance Duel and Arms Race performance.
Instead of training directly at your highest troop tier, you deliberately keep Barracks at different levels.
You then:
- Train lower-tier troops during the week.
- Stockpile them.
- Promote them through the staggered Barracks.
- Receive event credit at each promotion stage.
This can produce substantially more event points from the same troop development resources.
Current troop references explicitly document that promotion through multiple levels can earn points at each level, while the overall training time/resources remain approximately the same. citeturn1search0
Why Waterfall Training Works
Suppose your Barracks are arranged so they can reach:
T5 → T6 → T7 → T8 → T9
Instead of:
Train directly to T9
you can:
Train T5
↓
Promote T5 → T6
↓
Promote T6 → T7
↓
Promote T7 → T8
↓
Promote T8 → T9
Each promotion represents another troop progression action that can contribute to event scoring.
The exact point values can change with game updates or event rules, so use the current event interface as the final authority.
Waterfall Barracks Setup
A common four-Barracks example is:
| Barracks | Level | Maximum Tier | |---|---:|---:| | Highest | 27 | T9 | | Second | 24 | T8 | | Third | 20 | T7 | | Fourth | 17 | T6 |
During the preparation period, train troops at the lowest practical tier supported by your setup.
Then on the scoring day:
T5
↓
T6
↓
T7
↓
T8
↓
T9
Another possible setup is:
| Barracks | Level | Maximum Tier | |---|---:|---:| | Highest | 24 | T8 | | Second | 20 | T7 | | Third | 17 | T6 | | Fourth | 14 | T5 |
Then the chain can be:
T4
↓
T5
↓
T6
↓
T7
↓
T8
The key principle is:
Your Barracks should be deliberately staggered if your goal is maximum event scoring.
Current references document these tier thresholds and staggered Barracks strategies. citeturn1search4turn1search3
Waterfall Rule
The simplest rule is:
Train at the lowest tier you can efficiently produce, then promote upward through your Barracks on the scoring day.
Do not blindly copy someone else's Barracks levels.
Your ideal waterfall depends on:
- Number of Barracks
- Highest troop tier
- Current server/season
- Event schedule
- Training resources
- Main combat requirements
Waterfall Training Weekly Routine
A typical weekly cycle is:
Preparation Days
- Train low-tier troops.
- Keep Barracks active.
- Build a stockpile.
- Save training speedups.
- Save general speedups when appropriate.
- Prepare food and iron.
- Optimize Survivors for large batches.
Training / Total Mobilisation Day
- Promote troops through the waterfall.
- Use saved training speedups.
- Use eligible general speedups.
- Continue feeding new low-tier troops into the chain when possible.
- Coordinate with your alliance.
After the Event
- Rebuild your low-tier stockpile.
- Replace troops lost during PvP.
- Prepare for the next event cycle.
A current Alliance Duel reference identifies Total Mobilisation as a major training-focused day and recommends waterfall promotion as part of the strategy. citeturn1search2
Waterfall vs Direct Training
Direct Training
Train T9
Advantages
- Simple
- Immediate high-tier troops
- Useful when you urgently need combat troops
- No special Barracks setup required
Disadvantages
- Less event scoring potential
- Less efficient for competitive event optimization
Waterfall Training
Train Low Tier
↓
Promote
↓
Promote
↓
Promote
↓
Highest Tier
Advantages
- More event points
- Better use of the same training progression
- Excellent for Alliance Duel
- Excellent for Arms Race training phases
Disadvantages
- Requires preparation
- Requires staggered Barracks
- Requires more management
- Can be inconvenient when you urgently need high-tier troops
When NOT to Use Waterfall
Do not let event optimization hurt your actual army.
Train or promote directly when:
- Your main marches are underfilled.
- You are preparing for an important PvP battle.
- You need high-tier troops immediately.
- Your alliance requires immediate troop strength.
- Your server is entering an important combat event.
- You have insufficient reserves.
Event points are valuable, but combat readiness comes first when a real battle is approaching.
Training Speedups
Training speedups are one of the most valuable resources for troop development.
They can be used for:
- Normal troop training
- Promotion
- Event scoring
- Rebuilding after PvP
- Preparing for major battles
Do not automatically spend them whenever you have an unfinished training queue.
Instead, ask:
Do I need troops now?
↓
YES → Use speedups if necessary
↓
NO
↓
Is a high-value training event coming?
↓
YES → Save
Training Speedups and Alliance Duel
Training speedups are particularly valuable during training-focused Alliance Duel scoring.
Current event references identify Day 5 / Total Mobilisation as a major speedup and troop-training scoring window, with training receiving a high event multiplier. Event schedules and scoring can change, so always verify the current VS screen. citeturn1search2turn1search5
A competitive routine is:
Monday–Thursday
Save training speedups
↓
Prepare low-tier troops
↓
Friday / Training Scoring
↓
Use speedups
↓
Promote waterfall
↓
Collect event points
Training and Arms Race
Arms Race can also contain troop-training or unit-progression scoring.
When a training-focused Arms Race phase is active:
- Complete planned troop training.
- Promote prepared troops.
- Use appropriate speedups.
- Take advantage of the event without disrupting your larger progression plan.
The exact schedule can change, so check the current Arms Race interface.
Troop Training and Resources
Training consumes resources.
The main resources involved are generally:
- Food
- Iron
- Gold where applicable
- Speedups
Low-tier training normally requires fewer resources per troop than high-tier direct training, which is one reason waterfall preparation is practical.
However, the correct strategy is not to save resources at the expense of combat readiness.
Maintain enough resources to:
- Keep training active
- Fill your main squads
- Recover after PvP
- Participate in important events
Troop Recovery After PvP
PvP can create large troop losses.
After a major battle:
- Check your Hospitals.
- Heal injured troops.
- Check your Drill Ground.
- Identify how many troops are actually missing.
- Start training replacements.
- Use saved reserves when appropriate.
- Restore your main marches first.
- Rebuild your waterfall stockpile afterward.
Do not spend every training speedup immediately if the next major event is close and your combat situation does not require it.
Training Priority After Losses
When rebuilding after PvP, prioritize:
- Main squad troop capacity
- Main troop tier
- Additional march requirements
- Secondary squad troops
- Event stockpile
The exact priority depends on how soon your next battle is.
Drill Ground and Troop Capacity
The Drill Ground houses your trained troops and displays your available army.
It is important because your trained troop quantity must be supported by your overall account capacity.
A strong account should monitor:
- Total troop count
- Troop tier
- Available march capacity
- Hospital capacity
- Emergency recovery capacity where applicable
Current building references identify the Drill Ground as the facility that houses troops and increases troop capacity as it is upgraded. citeturn0search1turn1search0
Training Buildings vs Drill Ground
These buildings serve different purposes.
Barracks
Train and promote troops.
Drill Ground
Houses your troops and contributes to your available troop capacity.
You therefore need both:
Barracks
↓
Produce Troops
↓
Drill Ground
↓
House Troops
Troop Research
Research is one of the biggest multipliers for troop performance.
Research can improve:
- Troop Attack
- Troop Defense
- Troop Health
- Training efficiency
- Training speed
- March capacity
- Other combat statistics
Your troop tier is only part of your actual troop strength.
A T10 army with weak Research can perform worse than a properly developed T10 army with strong Research.
Research Priority for Troops
A practical priority is:
- Unlock the next troop tier
- Improve important troop combat Research
- Improve training efficiency
- Improve troop capacity
- Continue specialized combat Research
The exact order depends on your current Research tree and account goals.
For T10/T11 progression, the required advanced Research paths should be treated as major long-term projects rather than ordinary upgrades.
Troops and Hero Development
Troops amplify the value of your Heroes.
A squad requires both:
Heroes
+
Troops
A strong Hero lineup with insufficient troops cannot use its full march capacity.
Likewise, a huge army with weak Heroes will not reach its full potential.
The best results come from developing both systems together.
Troops and Equipment
Equipment improves Hero performance, while troops provide the army foundation beneath those Heroes.
Do not assume that better equipment can compensate for weak troop development.
Your main squad should have:
- Strong Heroes
- Strong Skills
- Good Equipment
- High-tier troops
- Strong Research
Troops and Drone
Drone bonuses work together with troop and Hero development.
A strong Drone improves the combat performance of your squad, while high-tier troops allow that squad to use its available march capacity effectively.
Troop progression should therefore be developed alongside:
- Drone
- Heroes
- Research
- Equipment
- Formation
Troops and Formation
Formation affects how your Heroes and troops perform together.
Your troop type should normally match your Hero composition.
For example:
5 Tank Heroes
+
Tank Troops
is generally more coherent than:
5 Tank Heroes
+
Aircraft Troops
unless a specific mechanic or strategy gives you a reason to do otherwise.
Troop Quantity vs Troop Quality
Both matter.
Troop Quality
Higher tiers provide stronger individual troops.
Troop Quantity
More troops allow you to:
- Fill marches
- Maintain multiple squads
- Reinforce allies
- Recover from losses
- Participate in more content
Do not sacrifice all troop quantity simply to increase troop tier.
Likewise, do not maintain huge numbers of low-tier troops while ignoring the next important tier unlock.
Common Troop Development Mistakes
Training Only at the Highest Tier
This is simple, but can waste event-scoring opportunities.
Better approach
Use direct training when combat readiness is the priority and waterfall training when event optimization is the priority.
Leveling All Barracks Equally
Equal Barracks levels can eliminate the staggered promotion chain.
Better approach
Use deliberate Barracks levels if you are running waterfall training.
Using Training Speedups Too Early
Speedups used before the high-value training event may produce less value.
Better approach
Save them when you do not need immediate troops.
Ignoring Survivors
Survivor bonuses can increase effective training capacity and other training-related benefits.
Better approach
Check your Barracks Survivor assignments before large training batches.
Training Without a Stockpile
If you only train when an event starts, you may not have enough troops ready for efficient waterfall promotion.
Better approach
Prepare troops before the event.
Ignoring Troop Type Counters
Using the wrong troop type against an enemy can reduce combat efficiency.
Better approach
Scout and choose the appropriate counter when possible.
Focusing Only on Power
Power is useful, but it does not tell the whole story.
Better approach
Look at:
- Troop tier
- Troop quantity
- Hero strength
- Research
- Equipment
- Drone
- Matchup
Neglecting Troop Quantity
A high-tier army that cannot fill your marches is incomplete.
Better approach
Maintain enough troops for your main combat requirements.
Over-Optimizing Events
A perfect event score is worthless if your army is too weak for an important battle.
Better approach
Prioritize actual combat readiness when necessary.
