While every side experimented with squads of specialised grenadiers, by 1916 the French army was the first of all major belligerents to adopt the squad and platoon as their infantry's main tactical unit. The need for tactical flexibility over the hazard-strewn trench battlefields, the increased spread of men made necessary by the threat of artillery and machineguns, and the introduction of rifle grenades and the Chauchat machine-rifle in every infantry company required a new tactical organisation. However, the advent of modern warfare would prove to be a bloody reality check for past visions of glorious charges and a big wakeup call to military modernisation. The first weeks of war saw French infantry rage forward with particular élan to emulate the notorious 'furia francese' of old. We'll need at least three parts to cover them all, by which time we'll be closer to announcing a release date. The French Army evolved into a complex organisation during WW1 with many specialised trades since we design our factions on historical accuracy the French will have a rather large list of units. Here's a first preview and description of some of the units in the French Army's tech tree.
