Sergeant

Sergeants are a pretty useful troop; their special ability is a solid benefit (especially since it helps all troops on the map), and they're decent units on their own. Like many special units, though, the fact that they only have 1 troop per squad limits their effectiveness against larger enemy groups, so don't use them as a primary fighting force.

Sergeants can be produced at the Academy of Officers for 250 steel, 200 ammunition, and 200 recruits. Sergeants, like other officers, use the same equipment as regular troops.

Unit research
This table summarizes all of the research that can benefit Sergeants. For full details, see the specific research pages.

Unit skins
Sergeants have five skins available, as listed in the following table. Some skins can be purchased with gold at the Academy, while others can currently be obtained only through special events. For the skins which are not purchasable with gold, the "duplicate value" is the amount of gold returned if you obtain a second copy of the skin. (For skins purchasable with gold, the duplicate value is simply equal to the purchase price.)
