He also helped train Fives and Echo after they were promoted to becoming ARC Troopers.
Blitz wears Experimental Phase 2; Armor from what the Experimental Phase 2 ARC Troopers wear; with yellow stripes and a unique white kama with black diamonds.

Most fans believe that the ARF Scout Troopers he commanded in the Clone Wars series episode "ARC Troopers" were from his squad, or from the rest of the Rancor Battalion, yet they are actually from the 104th Wolfpack Co. (Wolfpack).
Blitz's nickname wasn't revealed until Hasbro released the "Defend Kamino/Defense of Kamino" Battlepack or action figure pack from Hasbro with him featured.
Blitz and Hammer were the only two Experimental Phase 2 ARC Troopers who survived the Battle of Kamino.
