Because this "recruiting" video matches perfectly the many other videos showing the same scenario. Literally absconding 16 yo kids from their mothers arms right in the street. Mother is hysterical.
I could post videos of kids in full gear at the front.....who say they are doomed. DOOMED. No ammo, no shells, and in a caldron. Half of their unit has died. Lifespan of new recruits measured in HOURS like 4 hours.
Its a nightmare and a death sentence. Thats what you are cheering for.
