The buddy pair is hardly rocket science. For a start you have unarmed civilians outgunned. So you don’t need anything more than a one-man team so long as you are firing. The problem is the firing gaps. So you have to riflemen work together to cover the gaps.

They didn’t need much in the way of “borrowed tactics.” This was like a bank job.
