Guerrilla squad

The guerrilla squad is one of the more unusual units in the game. Unlike typical squads which are made up of a group of similar soldiers, the guerrilla squad combines four different types of units: 4 guerrilla squad, 2 guardsman guerrillas, 1 avenger guerilla, and 1 guerrilla demolitionist. The demolitionist, like the Imperial Demoman, fires a weapon that does splash damage, so it's very useful that you have the rest of the squad to protect him.
