Capturing

Infantry are the only units in the game that can capture buildings. A building that can be captured is usually a small white hut with a flag over it. Inside will be a desk with a radio. An infantryman has to get close to that desk, not fire and not make any sudden moves for approximately 1-2 minutes in order to capture. Neither side receives a warning that a building is being captured, so it's vitally important for the defenders to keep tabs on all the capturable buildings in town and communicate with each other. Attackers need to talk as well, to request cover for the capper and keep tabs on the percentage of the capture.

The radio to capture tells which depot it is

Once a building is captured, the town becomes 'Contested'. You can check the status of the town you spawned in by typing ".own" (with the period, all chat commands in the game start with a period). If you want to check the status of another city, you type ".own CityName" (no quotation marks are ever necessary). A timer starts as soon as the city becomes contested. After 20 non-stop minutes of being 'Contested', a radio table appears in the bunker of the army base. The army base is the key to the city, it's what must be captured, and usually the last building to fall. Army bases are easy to recognize, they'll have several large green barracks for infantry spawns and a large, dirty green/gray garage that's used as a vehicle spawn area.

Keep in mind that as soon as a facility, particularly a spawnable, is captured in a town, the enemy will likely spawn in and look to get it back. An organized attack has the attackers already waiting to move in with their tanks and follow-up infantry. Depots quickly run out of infantry to spawn, so attackers will inevitably bring more in with trucks from the forward base.

Whether you're defending or attacking, keep an eye on the chat channel. It will not only make life a whole lot easier to know where the enemy has been spotted moving and firing, it will also notify you of captures in the town. Friendlies may try to warn you about "EI" (enemy infantry), "ET" (enemy tank) or "EA" (enemy air) coming your way or in your vicinity, and you should endeavor to do the same.

When taking on tanks, remember that they have poor visibility but someone with good headphones and volume turned up can hear you running or jogging up to him. A grenade in the commander's hatch can kill the commander and possible injure/kill the crew, but this requires a lot of accuracy. There's a small chance of crew or tank damage from a grenade thrown at it, but the odds aren't in your favor. Gun rounds into an open driver's slit can kill the driver, effectively nullifying most of the tank's value since its mobility is gone. Keep in mind that there's really no way to tell if a driver's slit is open, the tanks that have them visible on the outside always show them open even if they're not. Best to call in Sappers or ATGs your way.
