I meant the shooting in the back part and not the Soviet ideology part, since shooting soldiers in the back is not something the Soviets invented and it would have come up during our joint training with them and the Grave Tenders...
The Red Army may not have invented barrier troops, but they were the ones
most notoriously associated with maintaining discipline by reserving forces which could have otherwise been fighting the enemy for the explicit purpose of gunning down any of their own troops who tried to retreat without orders.
The 504's have demonstrated a willingness to tolerate monstrous casualties, and we see things like their troops wearing armor which several earlier people have clearly been killed in. We are not going to face serious diplomatic consequences for deciding not to get our troops killed to rescue them from their own objectively stupid decisions.
-and why would the need for barrier troops come up during a training exercise? The troops know that even if they lose they are not going to die, so they are much less likely to break and run and hence there is much less call for tenders intimidating them into running towards the enemy.
-hence why we need to charge to take advantage of the situation
-or why we should be cautious and fight like a firearm-armed modern military instead of a bronze age rabble. There is nothing to "take advantage of" here. The situation is
worse than if the 504 had never charged because we can't just tell our automatic-weapon-armed troops to start throwing lead at the enemy for fear of hitting our allies or withdraw and use our jaeger training to use the forest to slip around them. The advantage will come after the 504 either break the shield wall or die off and give us a clear line of fire on the weakened enemy line. Deciding to run up so that the enemy can drop grenades directly on our heads while we shove against our allies in an attempt to get close enough to start slamming rifle stocks onto the enemy shields while two lines of spears turn the whole front into a meat grinder is not going to "take advantage" of anything.
-even if its only one, it's still a useful mechanic hence their name as assault troops
Awesome-
so leave them to do the assaulting. There is no reason to have our ranged troops start trying to shove their way between the power tool and flamethrower-wielding maniacs taken with a blinding berserk fury amidst a smoky, deafening mess of a disorganized and tightly confined battlefield.
