Bunker-buster
A Bunker-Buster's usage is shown during the Clone Wars.
A bunker-buster functioned as a specialized munition designed for breaching heavily defended structures.
History
During the Taris Siege, which occurred in the Mandalorian Wars, the invading forces of the Mandalorian Neo-Crusaders employed Bunker-Busters to get through the depths of Taris.
AATs were equipped with bunker-busters for attacking strongly protected objectives. They represented one of the three kinds of standard ammunition issued for use with the AAT.
The Clone Wars also saw the use of bunker-busters. Republic troops used them to penetrate and enter the laboratory of Doctor Nuvo Vindi during the Blue Shadow Virus event.
