Semi-related question: are there any combat sports that feature team-on-team instead of individuals?
Football. And no, I'm not joking.
I feel I may have been misunderstood a bit. I was being incredibly literal in my comment that football (regardless of code, actually) is an example of a combat sport featuring team-on-team methods.
In simple terms many (it could even be argued all) sports developed out of tribal warfare and military training. Football is no different. This is a big reason why fans of one team or another get so excited (fanatical...) about their teams successes and failures, as well as any rivalries. It's a throwback to tribal warfare, where the other team is another tribe/village, and to lose is a great hardship on the community. So, the origins of football are based in combative exercises in teamwork, making it (ancestrally, at least) a form of combat sport... and it certainly focuses on team-on-team methodology.
I really wasn't being funny.
