But I'd say you have too few men-at-arms: knights, swordsmen etc. While they were usually outnumbered by the archers, they were in some ways the core of a medieval English army.

Billmen come in after 1400 or so, largely replacing spearmen. Both types would probably be less common when fighting in France than in the British Isles.

A lot of the mercs in M2TW could find a home in a historical English army. Merc spearmen, knights and crossbowmen especially before the HYW. Welsh spears and Irish kerns as well.
Ok, so revised, it would be:

1 general
1 english knights (dismounted if more men-at-arms are needed?)
1 dismounted english knights
1 swordsmen
1 retinue longbowmen
1 yeoman archers
8 longbowmen
1 heavy billmen
1 heavy bill militia
2 bill militia
1 irish kerns
1 levy spearmen

And if I wanted to recreate a French army (using two armies, so 40 units total) what would their composition be, 1300's or so?
