My understanding is the Stingers issued to Afghan "patriots" during the campaign would be pretty much useless now anyway...batteries dead (and they don't use "D" cells), heat-seakers ageing and slightly on the decrepit side etc etc etc. Sometimes a limited shelf-life (or "Fire before date") ain't such a bad thing after all.
The SA-7s are a worry though. Welcome to the 21st century. I suggest you fasten your seat-belts firmly...it's going to be a bumpy ride.
