Sabre used in ISDF17

[DarkCobra262]

Well for a new player the sniping of sentries might not be such an obvious solution as they have no idea what lays ahead.
As it is you would need some serious combat skills to get your tank through the mission, unless you take lots of tea breaks
The thing with games is how to make them hard, without making success just highly unlikely or even worse boring, which the tea break solution is.
I'm not advocating any alterations, but personally I would have put a lot more action, weapons, health and ammo into the last mission.

This is something I would do as well, or give the player something along the lines of "Experimental Sabre" that regenerates health xD
