Hi
Presently German Infanterie Squads start out at 12 people, then in 1944 the number of men drops down to 10.
However, the Germans already adopted the 10 men squads in 1941, while still maintaining 4 squads per platoon.

The three squad per platoon organisation (called Inf Kompanie 44 ingame) was adopted in Spetember 1943 and had 9 men per squad.

Moreover, the Volksgrenadier platoon had only 8 soldiers per squad, as opposed to the 12 ingame right now:

You can also see that the rifle squad of the Volksgrenadier Platoon should probably receive the MG42 (2) weapon from the Panzergrenadier squads.
