The Universal Carrier is a thinly armored tractor designed as a squad transport, light support vehicle and Scout. It fulfils relatively the same purpose as a scout car, harassing enemy units with its weaponry or ferrying infantry to capture points.
It comes with two upgrades; a Vickers .303 Machine Gun or a UT-2 Flamethrower but it will no longer transport infantry in that fashion; Turning UCs into basic assault vehicles.
Much like its wheeled counterparts, UCs are fragile and can be destroyed by enough small-arms fire, AT weaponry and tanks.
It is relatively uncommon to use these to supplement an attack and be treated more as a logistics vehicle; ferrying infantry and Royal Engineers to fortified positions.
