Vic is assigned to go out and capture a German prisoner, for interrogation, but he's sent out with three replacements for his squad who are relatively old, not promising candidates but he's stuck with them.
Kirby as usual is smart-alecky from the outset, clashing with the replacements, while Vic takes a wait-and-see attitude regarding their performance.
This story makes for an unusual (and logical) contrast to the more common situation of the squad having to deal with young, raw recruits, while exploring the underlying same issue of "cohesion", as the tried and true members of Vic's outfit need to mesh with clearly less reliable additions to their numbers.
Simon Oakland is fine as the replacement with a gimpy leg, but his reckless, gung ho attitude in an effort to prove himself gets the whole team into trouble. As a result, the heroes are soon outnumbered by Germans, fighting for their lives. The climax of them going up against a machine gun emplacement is exciting.
An all-time favorite character actor of mine, William Phipps, underplays skillfully as a case of a soldier who is quite homesick, frightened and not cut out for battle.
