armoured

Hello, So I have been looking into the army, aside from the fact that i have always been drawn to it, I'm sick of civvie life. I am immediately drawn to the infantry as I like the whole "purest form of soldiering" aspect. I love risks and doing anything that gets the adrenaline pumping, also...

Im applying soon and im not sure if i want to be a light gunner or an AS90 armoured gunner, anyone have any advice?
