... It has to be said they kind of are idiots...
They're in a war, the area the people they're looking for has been captured by the enemy, the hospitals nearby are filled with wounded soldiers, the army has to figure out how to respond.
And they think everyone should drop what they're doing to figure out what happend to their brother/son/nephew/.... ?
I get they want to know what happened, but to expect it right in the middle of a situation like this is just.... ridiculous. The Russians still aren't grasping that they're in an actual full on war that they started it seems? And that their men are dying and will be dying as long as it keeps going? And that everyone has far bigger priorities than to care about them?....
It's probably just a strategy to get them to shut up. And to make clear noone at the Russian army cares about them or their relatives that were sent to war.
