I have to agree with the first reviewer. The idea that Col Gallagher would bring anything to this party is laughable. Can't see a realistic scenario where the military would send a bomber group commander to Belgium to read captured documents and he doesn't read German!
I watch this episode on METV and the proceeding hour is two episodes of the "Rat Patrol". When this episode started, I thought I was seeing a third straight episode of that show. Belgium sure looks like a desert here. Not too realistic. Also, the German officer at the start of outing shows a weird lack of interest in all the shooting going on. He would pay for that mistake with his life.
I do like the action and the cast. These are all veteran actors who do the episode justice. Martin Milner did a lot of military roles in his long career. Check out his movies early on. Rudy Solari would be in "Garrison's Gorillas" a year later. Lawrence Montaigne, forever Spock's rival Stonn, was in "The Great Escape". Richard Anderson is always a pro. Everyone gets into the spirit of the thing.
Looks like they raided the "Combat" equipment locker as the halftrack with the added roof/machine gun made two or three appearances in that series. I think Milner is wearing Sgt Saunders camouflaged helmet. That is just wrong!
There are a few things to like here but because of the weak premise, I can't recommend this hour.
