Defines an InfantryType that will spawn from a destroyed construction yard. However, Red Alert 2 (and Yuri's Revenge) do not distinguish between factions so the Engineer spawned will always be the infantry defined by this tag.
Determines whether this InfantryType has the properties of an engineer, which allows that infantry to enter any structure that has BridgeRepairHut=yes set, capture any structure that has Capturable=yes set and to repair any structures owned by that player. In Red Alert 2 and Yuri's Revenge, this also prevents infantry from using a weapon on any object, should they be given one, except if the weapon has a warhead with BombDisarm=yes set, in which case it will be able to target and successfully be used on objects which have an IvanBomb attached. Weapons of any kind can be force-fired on the ground.
