OK, may have missed this but I noticed that HMG's are effectively covered as 'crewed weapons' BUT have the markings of a 'Squad' counter (with the exception of the little 'c' next to defense).
This is confusing at first glance as it seems like they would or could have some level of effectiveness against very light armor. I see now that since there is no range chart one can assume that it simply cannot shoot at any armored weapon. The exception seems to be firing at 'open topped' vehicles and of course trucks (no armor).
This hybrid approach is confusing when new to the game. Perhaps they can be delineated better in future rules. I honestly was not 'sure' for a while if all the captured rules apply to them (HMG) or not. I am assuming they do, please correct me if not.
