Okay, I have a few things to say.

First of all, Always listen to your commander. ALWAYS, never mute him, even if he is annoying. If he sucks, mutiny, and get a good, trustworthy person to replace him.

Secondly, think of all the ways you could use tanks. Just shut up, and think.

Thirdly, I have a small guide on using Tanks and APCs. Here goes:

Tanks---

What do you do when you have to attack a city or town? You mass together a few tanks, and an APC or two. The tanks destroy vehicles, and defend the APCs, while said APCs unload troops and, of course, go get more. Another thing, always have an Engineer in the tank, and Support as the driver. Gunner is now as important as the driver.

Now, I don't know why, but it seems that whenever I think of the word "Convoy" I also think of massive explosions, strafing and bombing runs too. Simple solution though. Use the APCs' rapid, Anti-Armor/Air cannon to defend against Choppers and other aircraft. In BF2142, the APCs have EMP grenades. EMP + An attack gunship = Crash. They can disable enemy tanks, too, and screw with the NetBat devices of the ground troops. On BF2, APCs and other IFVs have TOW missiles, which are guided by moving the camera. Use them wisely, because shooting one into a MIG or SU-27 coming straight at you WILL do lots of damage.

On another note, the APC Driver, and Gunner (If applicable) should be Engineer. Kind of obvious.

I hope you enjoyed this suggestion, now gimme some of yours. Now.
