Comment 2 for bug 894992

It might need another tag, thinking about it. as my mine layer has a light machine gun ATM, to defend itself once it's out of "mines" so I wouldn't want the machinegun using ammo pips which are set as mines.

It could be solved by having a MineLayer=Yes tag, and the mines as a secondary weapon, so the logic will identify the mines as being rechargable, whereas the machine gun is infinate.
