"We took them with the airsoft guns because it's our hobby and we wanted to include them in the pictures," Pereira said.
The guns shoot plastic pellets and the students play games with them in designated fields – much like a paintball game.
They worked to save up for the guns and the games are a big part of their social life, they said. So they posted the picture on social media and tagged it "Homecoming 2014."
