All those "days" reminds me - I was in the then Kiev and it was some sort of national day. There were hordes of kids on the streets, all marching with shouldered rifles. The youngest would have been about 8! I took the pictures and they'd done their bit and their leader bloke wanted to use/show off his English. Not a lot to talk about really, but I recognised their guns. Some Tokarev carbines, and two of the kids had Mosin-Nagant sniper jobs, about at long as the kids were. They were telling me how far away they could kill someone - easy ish because you learn numbers if you're travelling. Then it got difficult. They wanted to know something about me in "military" - er, no. I'd clocked the M-N sniper rifle because I'd recently looked it up, it has a strangely high sight.
The reason I'd looked it up wasn't because I'm some highly knowledgeable student of soviet munitions. I'd just read an Andy McNab book and one if his characters used one for an assassination...
