Hi David,
CH46 could carry two squads so 2PP, they usually mounted 2 M60s, so I'd give them a 2*. Only 2 because we let them fire 360, which signifies one in each door. They should have an armor factor of one.
BTW, there is a VERY active LnL forum at Consimworld (
www.consinworld.com).
Happy Holidays,
Mark
