Tactic: When people are in tanks and they blow a hole in a wall, wait a second, THEN go through it. I have seen so many dumbasses walk in front a tank shell when they could have gone earlier, then screaming about how the driver was a "TeAm KiLlInG NUBZORS!!" when he was trying to hit a heavy with a minigun........
Tactic2: Teamwork you handicaps. Jump on top of each other to reach higher places, not whining about how the hole is too high to reach. Have 1 or 2 tanks fall behind and work as artillery to soften up the enemy, then rush them with jeeps and planes. Tip, wait 30 seconds before you drive off in a jeep. Sometimes it can help to have 6 infantry units rush in and kill the enemy, then run out with the flag, jump in the jeep, get back to base, profit! Sniper cover is helpful also, snipers are not limited to killing infantry, they can damage vehicles too. Then when the vehicle or its driver is killed, you can pick off the survivors/passengers. USEFUL TIP: Use the . to move around in vehicles. Once in nooblet's server there a dude who thought to get in the turret of the tank was to jump on the turret, he kept on getting pissed when he ended up it the gunner's seat. I told him to press period, but he was just too much of a noob to understand....
Double toast :3
