This is the first appearance of the WWII Suicide Squad. The stories that appeared in issues #110 and #111 did not actually feature any group called the "Suicide Squad". The PT boat squadron in those two issues is referred to as a "suicide squadron" in the title of issue #110 only. See issues #110 and #111 for details.
First appearance of Morgan and Mace. Mace was an Olympic bob-sledder, who's partner was Morgan's brother, Bill. Bill Morgan died in a sled crash, and Vic Morgan blames Mace for it. The characters appear in #116, 117, 118, and 120.
