These are hooligans. They are addicted to fighting. What’s funny about hooligans, is that rival groups text each other and arrange to fight, it’s not personal, it’s feeding their addiction, that’s what most people don’t get about hooliganism.
If only both sides are supplied with guns, it would make for a very quick “hooliganism”. All they do is throw arm punches/missed kicks and, may be, occasionally throw objects. Definitely not efficient as they could be.
