Do you realize how much effort and resources are expended in raising and training 100 human beings? That's thousands of rounds of ammo not being shot at Ukrainian soldiers, because dead men carry no guns, operate no equipment and don't pass on their experience to new soldiers.
It's all around horrible what's going on, but 100 soldiers are no laughing matter. Robotyne was defended by 4 soldiers at one point some weeks ago. Russia has been trying to retake that village since they lost it last year.
