My army rp is pretty good. It has a front gate, a long plane strip, two military jeeps (not the default ones) in two separate garages, only allowed to be opened by major's. A huge hangar, probably half the size if it was scaled to 1:1 real life. It contains two vehicle spawns, each with their own separate vheicle chooser where you can pick 5 different planes. The hangar has two huge doors which allow the planes to exit. I do training sessions where we drive/fly to the afghan save, which has a long road from it leading to the base, and there's bots located randomly which randomly wander. The troops have to get to the roof of the blue house where they get escorted by helicopter back to base. They sometimes do laps of the base, we do flight training where they have to lift off, travel at high speeds and hit a stationary/mobile jeep on the ground. They have two chances , if they don't hit it within those chances then they fail. Also if they crash. I have 6 ranks, each with their own separate armoury. Only that rank and above can access their armoury. So a private can't access a lieutenant, but a lieutenant and major can. I can't remember what ranks I have, but yeah you get the idea.
And oh yeah, the thing is with that many ranks, tdm can only handle 6 :/
