I've found many things about the Land Carrier:Hiding Spots, (otherwise) thought impossible reachable locations, some fun things to try when the level laggs extremely, tactics, and more.

Ok, so do you know about the Mantel helicopter in the middle of the level,above the SQL card? Well, as a Mantel Trooper, go ahead (and it would be a good idea to pack a sniper rifle) and Nectar up and jump over the rail and onto the wing that extends outmost to the platform. Jump over onto the wing, then carefully make your way on the Heli. Bam, you're done!

Thanx for the tip! also, i have found out that if you go up in one of the sniper positions you can pick up the sniper rifle and keep your D6 pistol so you can snipe people and when someone comes up the ladder to kill you... BOOM! Note: the ammo regenerates itself for the sniper if you stay put. Also, if you play as a rebel and want to try it out you can always
A.steal a pistol
B.throw knives instead
C.do whatever you want
D.set 'nade traps
E.bring some pain with the SHOTGUN
