Pat, are you saying the AGL is not used if the unit is equipted with the ATGM ?? We already have two versions of that unit in the OOB's.........one with the ATGM and one without but they both have the AGL and what you appear to be saying is this vehicle either has the ATGM or the AGL... not both.
Also, to add to the confusion this website you posted
http://kurganmash.ru/en/turrets/turret_bmp2/ claims, under "BMP-2 Turret" the ammo load as
| Ammunition allowance | |
|---|
| 30-mm APT, FT and HEI cartridges for 2A42 automatic gun | 500 pcs |
| 7.62-mm cartridges for coaxial PKTM | 2000 pcs |
| 81-mm smoke grenades for 902V system | 6 pcs |
| ATGM | 1 piece |
.......... really..... 1 missile ?..... that's what it says but I have seen the photos of the vehicle with two launchers on each side of the turret but it does appear to be that you either get the missles or the AGL
