Grenade units are medium-range units that fire grenades in a straight line. The grenades are able to bounce off of all in game obstacles; but If you fire a grenade while standing near a waist high object it will pass over. Grenades, unlike rockets, are purely anti-personnel explosives. This means that while units are damaged by the blast walls remain unharmed. Because the grenade unit needs to be instructed to fire it is vulnerable to other units if left in the open. The grenade unit is best paired with a shotgun for cover fire.
