I'm not sure this belongs in StratOps, but since SO deals with campaign play, I'm putting this here based on:
"The size of a vehicle’s crew is rarely important in a single game, but frequently becomes important in campaign play." TO pg 218
The question is, what effect does an under-sized crew have on a vehicle? I.e. you're playing in a campaign, which tracks all individual soldiers. You salvage an Ontos, which 'requires' a crew of 7*, however, you only have 3 tankers available.
Can they not sufficiently crew the tank and as a result it cannot be used in a TW game? Or is there some penalty (skill or otherwise) for having an undersized crew?
* Note: 7 is based on: "To determine the number of crewmen, divide the tonnage of the vehicle by 15, rounding fractions up." TO pg 218
Edit: Question refined below.
