if you look on the north east side of town (opposite where you spawn) there is an RPG on
the ground with 2 shots, and i cannot remember where but there is a grenade launcher
around somewhere too

pick up an ak47 and just keep on shooting it will go down eventually

Restart and select the grenade launcher as your weapon!

There are plenty or RPG's hanging around the outsides of the village. Grab as many rounds
as you can and try hitting the damn thing it is hard but you will get it.

took seven attempts couldnt find grenade launcher or RPGs just kept shhoting helicopter
and blokes ubtil it blew up
