Troop Training, Promotion and Healing Explained

The Barracks is where you train units. Its training capacity sets the size of a batch. Training speed is a separate benefit, so increasing the batch limit does not mean that the same batch will finish sooner.

The Barracks level table shows a training capacity of 30 at level 1, 370 at level 10 and 570 at level 30. These figures describe one building's training capacity. They are not the number of units a squad can deploy or the capacity of your Drill Grounds.

Additional Barracks give you more training queues. That is useful when you want to train through several buildings instead of relying on one queue. When comparing upgrades, decide whether your immediate restriction is the size of a batch, the time it takes, or the number of queues available.

Unit level has its own requirements. The training screen can require a higher Barracks level, and Tier 10 units require the Unit X technology. Read the requirement on the unit you want to train before spending resources on a capacity upgrade.

Promotion upgrades existing lower-level units. It is useful when you have units from earlier stages of your base's progress and want to bring them up to a higher level.

You need eligible units to promote, and the Barracks must meet the requirement shown for the target level. A message saying there are no units available for promotion is different from a message asking for a Barracks upgrade. Check both the available unit count and the target level before treating promotion as a replacement for your next training batch.

Training and promotion also answer different needs. Train when you need additional units. Use promotion when your existing units need a higher level. If the problem is an underfilled squad, compare its assigned units with the troops available in base rather than assuming that promotion will increase the number of units you own.

The Drill Grounds has a unit-capacity limit. When that limit is reached, the game can block a transfer of units. Making the Barracks training batch larger does not increase this limit; upgrading the Drill Grounds does.

For the first Drill Grounds, capacity is 1,000 at level 1, 3,000 at level 10 and 7,000 at level 30. Additional plots have their own level tables, so use the table for the plot you are upgrading.

The unit overview separates units in base from units outside. Check those counts when a formation has fewer available units than expected. Base capacity and the units assigned to one squad are different limits, as explained in Squads Explained.

The Hospital handles injured units. Hospital capacity sets how many it can hold; it is separate from both Drill Grounds capacity and the number you can train in a batch. One Hospital holds 650 at level 1, 1,100 at level 10 and 2,000 at level 30.

You can heal a portion of the injured units or choose Heal All. The game remembers your choice in a specific way. Healing only some units saves that batch's healing duration as the default for future healing. Choosing Heal All clears the saved duration and preselects Heal All next time.

If you lack the resources to heal everyone, the game heals as many units as your resources allow. Check the selected quantity before starting, especially when you expected a full recovery. A shorter batch may simply mean that fewer units are being healed.

If a training batch is too small, look at Barracks capacity. If a unit level is locked, follow its Barracks or research requirement. If a transfer is blocked by the Drill Grounds limit, inspect that building's capacity. For injured units, use the Hospital's count and healing selection.

Once units are available again, check the formation before deploying. The game warns when a squad has too few units or unused capacity for its highest-level units. Training or healing may have solved the shortage at home, but the team you send still needs the right units assigned to it.
