What is crater warfare?

Crater warfare refers to a military strategy that involves the use of artillery to create large craters on the battlefield, which can alter the terrain and disrupt enemy movements. This tactic was notably employed during World War I, where the extensive trench systems made traditional warfare less effective. By targeting specific areas, armies aimed to create obstacles for the enemy and establish advantageous positions for their own troops. Crater warfare can also serve to demoralize opposing forces by showcasing the destructive power of artillery.
