Ok, here we s my stab at the French. I am interested in doing them myself and eventually. My limited understanding was the platoon leader could shuffle troops around sections as needed, ie concentrate his rifle grenade launchers.
Here’s how I would do it, if we are lucky someone with better knowledge will chime in.
April 1916 – October 1917
1 bombing squad
1 chauchat squad (as Lewis squad)
2 rifle squads with additional option for rifle grenade attack with D3 damage
October 1917-October 1918
2 x bombing squads
2 x chauchat / gl squads, which may fire as a Lewis Section OR a gl Section. Don’t forget that rifle grenades ignore overhead cover, but do d6-1 damage while the chauchet gets the -1 to hit, so depends on your tactical situation
how does that sound?
