Page 5 of the manual:

Important: note that a unit may not qualify to activate equipment if is it pinned, disrupted, heavily damaged or inside a fortification (pillbox).

1) When a squad is heavily damaged?

2) A squad with only a officer can activate an anti-tank guns?

Thanks

1. A squad is never damaged. Thus the rule suggests that there might be equipment usable for vehicles some day.

2. Yes, remember the figures are only an abstract of actual combat abilities. That officer is not a alone, someone has to wash his socks! ;-)
