I am not distorting the facts, but trying to cut off topics for a pointless argument in advance. It is not about a careless attitude towards one's soldiers. History knows many examples when soldiers in the numerical minority were able to hold back the enemy's advance. Nikolai Vladimirovich Sirotinin is an example of this. The man took the oath, knows his business, and really does not want his land to be trampled by the enemy.

You still don’t understand what I’m trying to convey and keep distorting the facts. I never said that barrier troops were "cowards." What I said was that you didn’t care about the lives of your soldiers, ordering them to fight to the last man even when defeat was inevitable. Those who retreated, knowing the fight was pointless, were sent back to die senselessly.

As for other armies using barrier troops—look at how only totalitarian states employed such units. The German Feldgendarmerie (also known as "Kettenhunde"), the Italian Black Brigades and Carabinieri Reali, and the Japanese Kempeitai all operated in a similar way. Western Allies did not use such units because, unlike you (referring to totalitarian countries), they actually cared about the lives of their soldiers. (Maybe the Italians cared a bit more, as they often surrendered when sent back to the front by their own barrier troops.)

That is, with all this I want to say that the barrier detachment is not a bloody evil KGB, but a formation that maintains discipline on the front line. Yes, the method is strict, even with excesses in places. But apparently no better solution was found. In addition, the barrier detachment is not cowards sitting behind the backs of their comrades, they also went into battle when necessary and also died.

The blocking detachments themselves were quite a normal practice in those years. Most of those who were caught trying to escape by leaving their combat positions were either sent back or to a penal company.
Yes, if you look at this topic head-on, it may seem that there is a bad company that sits out a few kilometers from the front line, they are not threatened by any danger, they themselves do not participate in battles and drive others to their death.
Information taken from open sources. 657,364 soldiers and officers were detained by the NKVD barrier detachments/special departments. The reasons for detention were varied: lagging behind their unit, espionage, panic, cowardice, desertion. 25,878 people were detained! and! 10,201 people were shot. The rest were returned back to their units.

I never said that there were execution squads in the rear shooting soldiers who retreated. In fact, I know they didn’t shoot soldiers who were withdrawing—although officers who ordered a retreat were often executed (see Dmitry Gluzdovsky or Fyodor Fomin).

Of course, there were some exceptions, like when General Chuikov’s 62nd Army was ordered to shoot soldiers trying to escape the city. Barrier troops generally sent fleeing soldiers back to the front, though in some cases, they faced field courts that resulted in executions—about 43,000 out of 440,000 deserters.

In battles, losses in the early stages of the war were associated with grueling battles, in some cases against greatly superior forces. Read about pervitin/Panzerschokolade, I can't speak for everyone, but the fact is that the Germans were shooting up.
Order No. 227: a favorite topic of anti-Soviets. Barrier detachments shooting from trenches into the backs of their own attackers. If you watch Russian films, like "Burnt by the Sun" or "Penal Battalion", and conclude that this is how it was, you know nothing about barrier detachments.
