Final acting role of Michael Alldredge.
After Gunnery Sargent Post (aka Harm) strongly encourages the recruit to climb the wall and the recruit successfully completes this with his superiors present, the scene switches to a red brick building with an American flag flying. It is labeled CAMP PENDLETON NAVAL HOSPITAL. This is the exact same scene used many times in Major Dad after that show moved to Camp Hollister.
The M35 Deuce 1/2 would not have gotten stuck in the mud so easily due to it all wheel drive capacity. You can see the front wheel drivetrain.
Actor Michael Cudlitz (Sergeant Tesla) will go on to make a name for himself as playing tough military characters, he goes on to play Sergeant Denver Randleman in the WWII mini-series Band of Brothers (2001) and Sergeant Abraham Ford on The Walking Dead (2010) and voices a U.S. Marine in the Call of Duty 4: Modern Warfare (2007) series to name just a few.
