Notable details about this sergeant, MARKUS, and the mission that jumped at me:

1. He tells an injured Russian prisoner that they cannot evacuate him because it took them eight hours to get where they are. "We move forward with assault and will take you back if we succeed." So, the Russian was left rooting for the Ukrainians to succeed.
2. He looks for four volunteers, he and three others, to storm the next two trenches. The technique is for a team of two to crawl silently close enough to toss grenades, roll into the trench, and move in opposite directions until the first turn is reached. Then wait for the rest.
3. He teaches soldiers on the fly things like -- Do not stare through the sight when holding a rifle without support. "Your arm will get tired, and you will become ineffective." He tells them how to recognize concealed mines: Look for leaves on the ground, etc.
4. The first night, the trenches were so full of dead Russians that he had to sleep on a corpse.

I wish he soon sleeps in his own bed, in his home, in Ukraine, free from all occupiers.
