These figures are from Old Glories WW1 range. The first squad to make it of my painting racks is 11 strong with a 2Lt. as the demi-section commander. It still lacks a rifleman with V.B. (grenade launcher) which should be arriving in a pack of grenadiers in a few weeks.
The plan is to begin with painting up a Demi-Section or sort of half-platoon. The French organization for a platoon differed from those of the other combatants and is closer to what the German Zug was in 1913-1914. A full platoon (known as a Section) was on paper 83-84 personnel strong, with a demi-section being closer to what a British / Canadian platoon looked like. I will be using the organizational chart for the 1916 to pre-mutiny 1917 French cosmopolitan army. Breaking down a demi-section further, we find that there is four squads, two rifle squads of 12 and 13 men respectively with each squad having two men carrying rifles equipped with V.B.'s or grenade launchers. There is also one 7 men HMG section and one 8 man Bomber / Trench fighter section. In total, with the added command, a demi-section will have ~42 men.
