There seems to be a common movie trope of soldiers or entire units who become disconnected from their chain of command, appear to have no mission or larger purpose, and often appear to be pursuing their own agenda or mission (which may or may not be strictly “legal”).
Now this can serve many purposes for telling a war story:
- Making a war story more personal or intimate - about individuals rather than an entire brigade
- Create a tense atmosphere of chaos and confusion as the larger picture may not be evident
- Portraying a military organization in a state of collapse or dysfunction
- Create sort of “Homer’s Odyssey” sort of tale where the hero (and his unit) traverse a surreal war-torn landscape people with odd characters
- Setting the characters up for some heroic last stand against overwhelming odds
Now trying to think of specific examples was a bit hard because there lot of grey area between “our unit went AWOL to pursue some Nazi gold” and “we lost comms with Bravo company”.
For example:
In Civil War, the characters encounter a sniper team engaged with some unknown shooter in a building. They seem to be cut off from their command for a long time with no particular orders or mission. Nor do they seem to be part of a larger operation or defending anything particular.
Another example:
Pretty much everyone in Apocalypse Now - Capt Willard, Col Kurtz, the crew of the PBR, Col Kilgor’s Air Cav unit, the firebase defending the bridge that kept getting blown up. Sure, they weren’t all “rogue”, but at the very least they all seemed a bit “freelance” in the executive of their orders.
Final Example:
In last act of the movie Fury, why would Wardaddy and his crew decide the best course of action is to engage an entire SS infantry battalion from their busted tank? At best, they could only have expected to delay the Nazis long enough for them to encircle the tank under cover and then blast them with their Panzerfausts, and then continue on to their objective. Or just go around them as the tank was immobile. I feel like the actual protocol would have been to abandon the tank or at least sent a runner back to the higher command so a proper counter-attack could be mounted.
So how realistic is this? While war is often chaotic, militaries are typically well organized. They operate in units and hierarchies. Those units need to be resupplied and rearmed from time to time. Platoon leaders notice if one of their tanks is missing. Battalion commanders tend to notice if one of their companies hasn’t checked in. If a bridge is strategically important to the entire operation, command probably won’t leave its defence to whatever rag tag group of misfits happen to be in the area at the time. When soldiers or small units get separated from the larger army, I assume they try to link up with friendly units ASAP, not find some obscure objective to fight to the death over.
