Bazooka Unit

The Bazooka Unit (監獄弾バズーカ部隊) is a battalion of one thousand human soldiers who guard Impel Down. They first appeared in chapter 543 and episode 445.

Appearance
Each member wears a militaristic-styled uniform, with sunglasses, rather than the torturers' style.

Abilities and Powers
Each soldier wields a bazooka that shoots powerful bullets.

History
They were ordered by Vice Warden Hannyabal to guard the stairway that connects Levels 3 and 4 in order to stop Monkey D. Luffy and the other escaping prisoners. When Marshall D. Teach suddenly appeared, they were all sucked into his darkness and were regurgitated, causing them to faint from the pressure and shock, thus annihilating the entire squadron.
