Can a squad firing a Gun (as a non-qualified friendly MMC) also use its inherent FP?
I say yes, because of "A9.11 MMC USAGE: A squad may fire any one SW MG at no cost to its own Inherent FP"
But my opponent says no, because a Gun is not a SW.
We could not find anything in chapter C that gives us the answer.
If a Gun is not treated like a SW for A9.1 (because a Gun is not a SW). Then Someone could try and argue. That a crew can fire two (or more) Guns in one fire phase. Because it is not restricted by A9.1.
As to your second question, as if a crew can fire two (or more) guns in one fire phase, the strain goes a step more: As per A5.4: There is no stacking limit for ordnance or SW, although the number of crews/HS which may function as Gun crews in a Location (A5.5) limit the effective use of Guns in a Location to three. But by A7.352 and A7353 I should say that a crew is limited to only one SW/Gun. <edit> Indeed, reflecting on the rule, a crew MUST be asigned to only ONE Gun. A crew Manning a Gun is considered a MMC counter, so an hex with only one Crew could contain infinite Guns. But that's again against common sense: A crew man a Gun. To man another has to move and expose itself, has to prepare, aim and fire… Too many film heroes here… Change the Gun to man, if you want… but in another game phase<edit>
