100th Infantry Battalion
Military Training: Camp Shelby
At Camp Shelby, Moriso becomes a member of an 81mm mortar squad in the 1st Battalion.
By April 1944, the 442nd is deemed ready for overseas duty. The 1st Battalion is renamed the 171st Cadre Training Battalion and is held back at Camp Shelby to train new recruits.
The 100th Infantry Battalion joins the 442nd RCT in their place. In acknowledgement of its performance, the 100th is allowed to retain its designation and the team becomes the 100th/442nd RCT.
