Arnold Merrit played Jerome Crown in 3 episodes in season #1.
"Rear Echelon Commandos"
"I swear by Apollo"
In all 3 he takes command of his part. Why Merritt was not made a part of the squad in the following seasons is a shame. He would have mixed well with actor Jack Hogan (Pvt. Kirby). Together they would have really added some human conflict to the show. (gambling, fighting, etc...)
They would have given Sgt. Saunders and Lt. Hanley several headaches.
Arnold Merritt appeared as Pvt. Cole and then as Pvt. Fisher in 2 episodes in following seasons (only to be killed in action).
