AAV-7 ... carrying 25 soldiers with 3 crew
In over 20 years of working in amphibs I can honestly say I never saw the AAV-7 carrying that many troops (let alone combat loaded troops). More common was about 12-14, maybe a few more in non-operational situations (e.g. familiarization rides).
The 2nd Airborne are no slouches themselves, but they lack armoured support.
What, no BMDs? I thought that was more or less standard fare for Soviet airborne formations.
