Fudge - another scale to tempt me.
I question the addition of rifle grenade teams to late war German TO&E. By 1916 - 1917 the Germans had phased out rifle grenades (which they previously had been employing primarily in defense, unlike British and French practice which certainly did include such teams) in favor of the Granatenwerfer (not included in this 77 R. Div. battlegroup), which by today's standards would be considered more on the order of a light mortar. Also, by this period there should be at least one (and later two) "light" machine gun teams (the MG08-15, a weapon far more likely to be encountered than the German smg) per German rifle platoon (which they have included in the Stoss platoon - I question that all of them are pistol equipped only, as most would be carrying carbines in addition to satchels of grenades. Pistols is how you equipped for a small level night raid, not a breakthrough). The British formation looked more accurate.
