Imperial Guard Heavy Weapon Teams

Source: Codex: Imperial Guard (1999), p. 5

Imperial Guard heavy weapons squads are crewed by a team of two men. Generally speaking, one crewman carries and fires the weapon while the other carries the ammunition. In game terms, the presence — or lack of it — of the ammunition carrier makes no difference to the way the heavy weapon is moved or fired. The ammunition carrier may shoot any weapons he is armed with in the same shooting phase that the weapon carrier fires the heavy weapon. Note that weapon teams stay with their unit at all times; they are not a separate unit of their own.
