The "Battle Beetle"

The Battle Beetle is a new tank designed and developed by several of the Sentinels to provide heavy fire support to Sentinel personnel in the field.

It was built on a coot, and is capable of both land and water travel.  The front section hosts the driver, as well as the possibility of a passenger.

The rear of the Battle Beetle houses the main gunner, his paint supply, and the primary weapon system -- 4 Tippmann A5s linked to the same firestorm crank mechanism.  It is theoretically capable of 60 BPS (counting all 4 units as one), which is perfect for the assigned mission of fire support against infantry.  The quadzilla is powered by two scuba tanks, allowing it to stay in the field all day.

The Battle Beetle had its debut at the 2008 Hunt for the Cure.
