Riflemen flares and Sprint should be merged into 1 Commander ability. Ez8 is fine, the Doctrine is what needs help.
Not sure what to do with the extra slot. Gotta be careful when you merge abilities and just add something (ahem, overwatch...)
Pull out white phos, fire up, flares, put in field defense, 1919, and the off-map from Infantry Company and this would be a lot better (plus the abilities would follow the commander theme instead of the strange mix it has currently).
I Don't see how this would be more in theme for the Commander. You removed two riflemen abilities that aren't on other commanders and added two riflemen abilities that are already on 2 commanders. The strangest thing thematically is Rear Echelon flamethrowers, but that should stay? I'm with you on the EZ8 point thats being said
Also this Commander seems to be about agressive tactics. M1919s and mines/bunkers are defensively minded abilities
