I went back to look at the man more closely. Given he's running for his life, his stride is short and unsure, and he quickly falls on uneven ground. This person does seem older, stiff in the joints and without stamina to make it around a corner.
And again he looks stiff and rather weak, unsteady on his feet as he's dragged to the car, he almost has the strength of an older woman (not a slam - I'm saying he's quite limited for a male facing death - this is his best adrenalin response)
But this has been a complaint now for almost 2 years - they were sending barely trained conscripts, people who didn't know how to hold weapons, out to the front lines and there was a report, loudly denounced as "lies, all lies" which said the more experienced men on the front lines said these unwitting conscripts last no more than 2 hours.
What you’re describing is what the United States did during World War 2 in Europe, due to a manpower shortage.
They were quickly trained and suffered enormous casualties.
“During World War II, conscripts who underwent abbreviated training due to manpower shortages were often referred to as “Replacement Troops” or “Replacements.” In the U.S. Army, they were sometimes called “Replacement Infantry” or “Repple Depples,” a slang term derived from the official Replacement Depots where they were processed and assigned to units.
In the British Army, the term “Z Reservists” was sometimes used for conscripts recalled for service, though they generally received more comprehensive training. In the Soviet Union, poorly trained conscripts were sometimes derogatorily referred to as “Cannon Fodder” due to the extremely high casualty rates.”
