The TDT is the ultimate deployable defense for GC - easy to build and low cost, it is a must for every base during its construction phase or while defending a perimeter. It also is used on most H.U.N. vessels for support against small aircraft. It shoots high caliber shells from either of the quatrocannons on both sides making it a powerful bombardment weapon with a high range radius due to it's moveable axis. Also deadly are both of the proton laser guns mounted on top , capable of a high stream of energy or single burst shots. The T.D.T. is also automatically operable as long you program it or you use from far distance as long as the relay antena isn't destroyed.
