I'm curious as to whether there will be different types of recon battalions. To my mind there were 5 types actually used in WWII:
Cavalry/Bicycle
Motorised
Mechanised - primarily infantry in light armoured vehicles such as German half tracks or British carriers but supplemented by armoured cars and/or light tanks
Armoured Car
Armoured - a late war mix of Lt & Md tanks
I guess the cavalry type could just be a cavalry battalion, as long as cavalry units get scouting bonuses.
Motorised recon battalions could similarly just be motorised battalions where they get scouting bonuses, or it could even just be an earlier version of the mechanised recon battalion.
If there is just going to be a single recon type battalion in the game, then it should be mechanised as it was the most widely used.
The only country I'm aware of that operated pure armoured car battalions was the British, so it might be easier to fold them into the mechanised category.
Again the only country I'm aware of that operated armoured recon battalions was the British, so maybe they should just be treated as Lt tank battalions.
