Sorry, not really up to speed on the AGLs myself, so will watch with interest.
Generally, as of 1976, dismount norms are roughly 8 men per squad (not including the vehicle driver, or commander/gunner).
I've read in the 1980s that dropped to 7 dismounts, generally.
MG assistants all carry AKMs.
BTR squads supposedly have 1 x RPK MG each, but none in the 10th HQ vehicle, so 9 x total for the company.
BMP-1 squads also have 1 x RPK MG per squad, and again none in the HQ.
Later BMP squads supposedly have 2 x PKMs per squad, per the DIA booklet (1976), which seems high to me, but perhaps those that they are referring to are the BRM, or BRM-1s. I originally thought they were referring to the BMP-2 units, but those weren't fielded until the 1980s, so that probably isn't right.
Then again, perhaps it is, and/or they're referring to the BMP-1P, or they had advanced knowledge of what the BMP-2 units were going to field in the 1980s, since they mention 10 x BMPs having 20 x PKMs (in the DIA booklet date 1976), and all of the recon units have fewer BRMs than that in them.
Not sure, so would appreciate clarification on that.
6 x PKMs total, in the 2 x BMPs (3 x each) of the attached MG platoon.
2 or 3 x PKMs total, in the 2 x BTR MG/ATGM platoon, plus 3 x AT-7 Saxhorns (not sure when those were introduced, but Wiki says they were available from 1978) – this is from the FM100-2-3 book dated 1991, so could be in the 1980s as well. Not sure if they'd have Saggers, Snappers, Swatters, Spigots, Spandrels, or recoilless rifles before that. Probably one of the earlier ATGMs in the mid-1970s.
1 x RPG-7, or later variant per squad.
3 x SA-7s per company – some list them as all 3 in the HQ vehicle, but I think they might parcel them out to avoid all their SAMs being taken out in one catastrophic hit. I've read both.
Hope that helps.
Best regards,
Rob
