Send a convicted killer with emotional control issues (and advanced weaponry) to a primitive planet and tell him to clean it up?
And then, when he screws up. send a fleet of flying saucers in to straighten out the mess.
(Martians apparently don't have a non-interference Prime Directive.)
Also note that the American military seems to be made up of idiot bureaucrats!
The writer for this premiere tale from Crusader from Mars #1 (1952) is unknown, but probably is the book's editor, Jerry (Superman) Siegel, who co-created another short-lived Martian crime-fighter, Lars of Mars, the year before.
Considering Stein was doing a lot of work for the Simon/Kirby studio at the time, and Jack was reputed to be very generous in terms of helping his friends, it seems likely he provided roughs for Stein to render full pencils and inks over.
BTW, you may note that Tarka wears a very Superman-style costume in this tale, but on the cover, and in the next (and last) issue, the colors are reversed.
