В атаку! Чего бы ни стоило!

Can be found in Simulated Universe 3 and Winter Soldier's March 1.

The phrase is often associated with battle, military strategy, or situations requiring decisive action. It implies a disregard for personal safety or potential losses in the pursuit of victory or achieving a desired outcome. In this context, attacking the Silvermane Lieutenant when his shield is up is a very bad idea because it triggers his counter attack. It takes madness (or a chive hunter) to do it 4 times in a battle.
