PMR-3 mine

The PMR-3 is a Yugoslavian anti-personnel stake mine. The mine is a development of the PMR-1 and PMR-2 stake mines, having a larger main charge and a greater effective radius. Two versions of the mine were built, an 'old' version and a 'new' version. The principal difference being that the 'old' model could be pressure and pull operated, while the 'new' model can only be pull operated.

The 'old' version consists of a cylindrical main body with six large fragmentation grooves running around the circumference and two mounting lugs on one side for mounting the mine to a provided metal stake. The 'new' version of the mine is similar, but with a smaller fuze and no fragmentation grooves.

The 'old' model of the mine is found in Bosnia, Chile, Croatia, and Kosovo. The 'new' model is found in Bosnia and Croatia.

gollark: Something like that might work. I guess that stuff isn't as important/sensitive as my other stuff and doesn't really need encrypting, so I could just sync it across pretty efficiently.

gollark: Though I'm not sure *what* I can do to usefully backup my 50GB of media, which is just archives of TV shows and YouTube channels and whatnot.

gollark: I'm awake then sometimes, but I guess it wouldn't be *too* horrible to do that at 2am?

gollark: Probably, but that would still be two hours a day or week or something of backups tying up the entire internet connection.

gollark: I mean, I would want to do backups often, and encrypted ones, which would prevent deduplication or whatever.
