[Airborne Rifles]

No need to apologize, and thank you for your service! It's something I love about this game and this forum, the commitment to realism and accuracy.

Think of the 82nd and 101st in similar terms to the USMC. they each have their specialized mission (parachute assaults and airmobile operations) that they conduct extra training for, but for otherwise they are just high-quality light infantry formations.

And you're correct, the light brigades in 1st and 3rd ID, and 1st AD were not implemented until the GWOT, though the Army had other light divisions in the 80's that have since been deactivated (7th ID, for example).
