Invicible Horse-art Bug is still with us, and worse than in Empire.
Both horse and foot “limbered” artillery are immune to small arms fire and melee combat attack, both standing or in motion. Cannon can still take them out, and under small arms fire they will rout, and can be killed when routing.
Moving through enemy firing range, they will draw (useless) fire away from infantry if they were the target first in range. So they can be used as a shield to a certain extent if placed in front of other troops.
