The Stal in the trench started to come out again after the tank attacked the soldiers behind the enemy lines, but bullets fell on them before they could reach Khan. The allies on the other side of the battlefield had targeted them as soon as they left their cover.
The help from the other platoon didn't improve Khan's situation. The Stal had gone back to the relentless but safe offensive iconic of the trench war, blocking one of the possible escape paths.
Khan found himself in a pickle. The two armored trucks were faster than him, and they could reach him before he arrived on the enemy trench. The battlefield had bullets flying everywhere, and the Stal in the channel had already started to point their rifles at him.
Khan was stuck between difficult choices. He could do his best to reach the allied barrier and hope to deal with the armored trucks along the way, or he could return inside the enemy trench and see if he could cause a mess again.
