For anyone interested, here is a working template for the company setup shown in the fifth video. The company is composed of 3 platoons of 3 squads, each squad being made of 3 fireteams + 1 lead team (3x3x4 = 36 groups).
Just extract the archive in your SP mission folder. The files are not binarized and can be read or edited with notepad++.
