Class battle?

Date: 6/20/2017

So I was in this sandy valley about 75 yards across. On one side close to the edge there was a train stretching the length of the valley. On both sides there was a trench stretching the length of the valley. I was on the side with the train. My whole grade was divided, half on each side. Everyone had an assault rifle and was battling. I was getting many kills but then I got shot in the thigh. I went into the train and got a bandage and that's all I remember.
