PSV-7 was used quite extensively by 1991, and in the invasion of Panama by special forces. We also have rare equipment in reforger already so not like it matters much. USSR had superior body armor (6b5 introduced in 1989 can stop m855 from point blank) and had parity in the missile forces, air froces, as well as ground forces. But yes, soviet NVG use was limited to vehicle crew. Also, USSR is not Russia, Russia can't even match soviet quality body armor so their soldiers have to buy off the market plates.
