Caspian Border

Caspian Border is a map which is featured in Battlefield 3. Caspian Border is a multi-faceted, vehicle heavy map that exemplifies classic Battlefield gameplay. In the video it shows that there are 5 points to capture with A being a gas station, B being a hilltop, C being a forest, D being a checkpoint and with E being an antenna (unavailable on consoles). It pits the United States Marine Corps against the Russian Ground Forces, on the border between Iran and Turkmenistan near the Caspian Sea, per its namesake. Despite its location, text on the gas station is in some sort of Roman script.

Writing in Farsi is also found on shipping containers, which suggests it is in fact in on the northern Iranian coast of the Caspian Sea, with the Alborz mountains in the background and in Battleblog #14 the Caspian Border is set in the Turkmenistan-Iranian Border.

Description
A Russian recon force has set up camp on the Turkmenistan side of the Iranian border and proceeded to take over the heavily built up border checkpoint.

Trivia

 * During the Battlefield 3 Beta, the Antenna had a ladder which could be used to reach an area on the antenna. The ladder was removed in the final version of the game.
 * When playing conquest, the antenna tower will collapse if any team has 10 tickets remaining.
 * The antenna can be collapsed by detonating C4 on any of the supporting wires.
 * On the console versions, mobile anti-aircraft vehicles and Flag E, at the antenna, are not present.
 * A patch came out for the release of the Back to Kardand DLC. This had allowed the Antenna to be destroyed once there are 10 tickets remaing.
