The medic

A grenade fell into the trench, he grabbed it and threw it back screaming for everyone to take cover. Dirt flew covering everyone.
The medic was behind the rubble of a fallen house the enemy fire wouldn't stop and the medic was out of ammunition.
He grabbed a rifle and started running and reached the medic without a scratch. He took off a pendant and put it on the medic at the same time as he drew a circle in the sand and cut a finger to drop his blood in the middle of it.
The circle became metal from the iron on the ground, and he took the copy of the pendant and put it in a jacket pocket.
" I'm sorry," he said as he grabbed the medic's head and forcibly pulled out the memory of what just had happened.
He put the medic on his back as he passed out from the extraction and he started to run back to the trench.
