At the last weekender my Italian brigade had a battalion gun attached. It was a single 4pdr with 3 crew. Treated just like a single gun battery with unlimited ammo and no need to refit, with no artillery park behind it.
Only moved at man handling speeds though, so was great on the defense like we were. Gives a good boost to firepower. Possibly too good that way.
Unsure whether a single battalion gun should get 3 shooting dice and cause resolve checks in the same manner as a battery. Possibly 2 dice with resolve checks or 3 dice no resolve check or even 2 dice no resolve checks. As various comments through the weekend along the lines of 'screw the battery just give me lots of 4pdrs' were heard
I also think they should dice for rounds too, to prevent indiscriminate long range sniping. In this way they are a handy boost to firepower for infantry formations but not some super weapon. It did chase a couple of Cossack/Tossack regiments off the board by causing them to fall back off board when beyond musket range of my rapidly forming squares(this happens when cavalry brigades miraculously appear between your brigade and the other brigade in your division
Strangely the French players weren't saying anything
