without watching the vids i could take a few guesses. (im at work)

1. there low lv musketmen, ie like militia musketmen or peasant muskets. ie untrained and not very coordinated. i would assume there would be some form of militia musket men

2. it possibly has to be researched (as stated above)

3. there is an option to turn it on off, while volley fire is effective once the battle breaks down, ur losing men from your line etc the discipline might break down or u might even choose to stop it and just shoot at will.

4. without having watched the vids i cant say for certain but was it staggered fire? with the time it takes to reload quite often units would stagger their fire in lines. first line shoots then second then third then by the time the 3rd or 4th shoots the first has reloaded keeping up a constant barrage.



my money is on 1 or 3. i would say there is either an option ie one option is volley fire the other is fire at will. or its just a discipline/skill thing.
