The problem with integrating snipers into squads (particularly in the Russian motor rifles) is the number of weapon slots. When you have to deal with a squad with AK-74s, one or two PKs, one RPG-7, the odd RPG-18, at least 2 BG-15 plus hand grenades, you don't want to top that with a sniper rifle or MANPADS.
As far as I'm concerned, I've modeled the Russian BMP/BTR platoon with three identical squads (AK/PK/RPG/grenade) plus a separate sniper and a separate SAM (optional). Notice that standard separate SAM team is 2 men, and that standard snipers are generally highly-trained units not consistent with the Russian doctrine. So both sniper and SAM I've copied into new mech infantry unit classes, both with a crew of 1 and a size of 1 (reduced concealment ability).
I'm not 100% satisfied with it, since both separate 1-man units tend to die a lot.

If you look, the official US OOB uses a similar trick for mech units regarding Dragon/Javelin teams.
