College is hard! There are all those books to read. Wouldn't it be wonderful to mix the workload up. Like, with some assault rifles?
These images reportedly show a popular class at Nanjing University of Science and Technology in China. The students are studying machine guns and taking them apart to see how they work.
While it might be surprising to most to see a college professor waving around assault rifles, if the students are going to study the weapons, this all does make sense. It's like dissection, but instead of frogs, there are automatic firearms.
