What's missing in MA training...

[dirk.bruere]

... is group on group work.
Coordinating attacks and defences as a group.
The soldier rather than warrior approach.
Does anyone anywhere train for that in MA?

[Panu Suominen]

Maybe soldiers do? Why would civilians need such training?

I have participated in group on group "fighting" in BJJ practices and coached some in shorinji kempo. Problem is that you don't often move with such trained pack so the training has little use in real life.

Some koryu have this training, which makes sense giving that many of them evolved with battlefield or similar circumstances in mind.
