A.7 GOOD ORDER: This term refers to a Personnel unit/inherent crew which is not broken, berserk, captured, stunned, shocked, or held in Melee.
From this, it can be clearly determined if an inherent crew is Good Order. Since Inherent Crews don't take counter form, do vehicles share the Good Order Status of their manning unit?
For context, A7.55 says "Good Order" units suffer Mandatory FG requirements. D3.5 says vehicular MG are subject to Mandatory FG. I have always personally used the status of the manning crew as a shortcut for the AFVs status but no rule states this.
