I figure I won't bother starting a new thread for this, but I decided I'd go and update the entire US Army AH-1 history for one of my OOB packs and noticed the following.
Unit 118 AH-1G Cobra - End date of 12/72. AH-1Gs were only finally converted completely into AH-1S starting in 1976. Suggest making them available until 12/76.
Unit 119 AH-1S Cobra - Cobra with M197 cannon and rockets only. AH-1S 1st and 2nd production run had the same Minigun/40mm AGL combo as AH-1G/AH-1Q, but with TOW capability. Up-gunned AH-1S/AH-1E had no rocket capability.
Also, start date is 1/73, but is equipped with hydra rockets and M197 cannon. Cannon only appears on Army AH-1S 9/78, Hydra 70 system not common until 1981. Should either have later start date (and revised name) or should have earlier start date and Minigun/40mm AGL combo and 2.75" FFAR (weapon 177)
Unit 120 AH-1 Cobra/TOW - Appears to be right for AH-1Q. However, should have same EW as AH-1S (EW 6)
Unit 121 AH-1 Cobra/TOW - Appears to be right for AH-1F. However, TOW-2A not produced until 1987. Should either have TOW or ITOW at this date.

Also, there's no AH-1G in the USMC OOB. USMC recieved AH-1G diverted from the US Army 2/69, pending arrival of the AH-1J.
