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.”
This isn’t WWII or 1945.
No relevancy.
Is it still 1942?
