This is simple and great for a quick way in and out of the enemy base, just make shure, if you are going to use it to exit when you have the flag, to put it somwhere easy to get to, and dont get it stuck in the hole in the base...thats just dumb. This is also good for retrieving your flag from an enemy flag carrier, just stay on his rear and dont stop shooting. In KOTH just go back and foth between the 2 bases and attack anybody you see to keep your guys in the hill safe, rendering your team more time. (make shure you dont fly in a strait path!!!)
This works extreamly well, if you order all your men to meet with you at a single spot (a easy to defend high spot is best) you can hold off enemy foces soo much better, especially if they are divided and leaderless. Anything that comes at you guys will just be decimated with your combined forces.
Ghosts are the best way to go with this, if you go to the enemy base (regardless if you get killed) with a ghost, hog, or banshee and put it right near an exit, you can easily (on your next attack) just walk out of their base and have a ride waiting for you. (this wont work very well if they have almost no vehicles to begin with becasue they will most likely just take it and use it because of their "low inventory")
