The US Army's 2nd Cavalry Regiment is conducting training exercises in Germany to prepare for a possible war with Russia. The regiment is based in Germany.

The training exercises involve a group of soldiers known as OPFOR who pretend to be the enemy during the exercises. OPFOR practices trench warfare as part of its role in the training.

The training requires an Army platoon to traverse mountainous terrain before finding the OPFOR's trench and attacking it.

Trench warfare has become common in the Russia-Ukraine war.
