Giant Squad

The Giants Squad (巨人部隊, Kyojin Butai) is the name given to a group of Giants in the Marine ranks assembled to guard the execution platform to be used for Portgas D. Ace's execution. They consist of at least eight Giants.

History
They were assigned to guard the execution platform. As the war with Whitebeard and the Marines began, they were told to be prepared from air attacks after Marco revealed his phoenix Devil Fruit powers. When Oars Jr. made his move, some of them tried to intercept the larger giant; however, he plowed through the Marine front lines and them as well.

Oars Jr. defeated Lacroix, Whitebeard knocked out Ronse with a single shock-wave imbued punch, and Monkey D. Luffy took down a third one (the one with a scar on the right side of his chest, with a scruffy medium-sized beard, wearing his Marine cap backwards, and wielding a club) with his Gomu Gomu no Gigant Rifle.

Members

 * Vice-Admiral Ronse‎
 * Vice-Admiral Lacroix

Trivia

 * Notably, one of the squad members is female, making her the first female giant to make an appearance in One Piece.
 * It hasn't been specified that the giant who fought Luffy is a Vice Admiral or not. If he is, then he would be the very first Vice Admiral to be defeated by Luffy in a direct confrontation, assuming that none of the other marines Luffy defeated along the way are Vice Admirals.
