knife kill, if you're in the UK there are a number of organisers who allow under 18s to event. Gunman and AGS spring to mind.
Also, you'll find that many people are willing to lend you kit so you should still be able to get along to quite a few events.
Gunman also has some hire kit, in the form of Bolt action rifles+ unifrom
WW2 Weapons AGM Sten, AGM MP40
as long as you can get there , the anarchy under the eagle event will allow you to play and you can borrow a uniform. all you wouls need is a gun

Actually basic uniforms actually *free* at Joshs Gunman battles, he's got a couple of boxs full of 40s and 40s-ish uniform and webbing folk can just dive into and borrow what they like.
