[SG2} House Rules for Fire Team Units

Untested, but these seem reasonable

1. The basic unit is a fire team, which is normally either a rifle
element (2-5 men) or a support weapon element (gunner and assistant).
2. Support weapons normally require two soldiers to operate.  The
assistant gunner is notionally armed with a rifle but does not use it
if the support weapon is functional.  If a support element drops below
two soldiers, it may fire normally on its own action but cannot
receive transferred actions.
3. The squad leader may leave any element without creating a
detachment, and may operate independently.  If he wants to join an
element (add his firepower, operate its weapon, etc), it has to
reorganize.
4.  A squad leader may transfer actions to elements of his squad.
5.  Morale penalties are calculated on the entire squad and affect the
entire squad.

Sample TOs:
NAC squad: 8 men = Squad leader + 3 man rifle team, 2 man SAW team, 2
man GMS/P team
IF squad: 11 men = Squad leader + 2x 3 man rifle teams, 2 man AGL
team, 2 man SAW team
