Battle in ETW will be different but the old tactics will still apply and are invaluable for even the most experienced tacticians out there. Mistakes will be that much more costly however, cavalry commanders for example have to know the right moment to strike because one volley will take out a cavalry unit and bayonets will mop up whats left of it.
One good charge however can be devastating but are you willing to risk it against my artillery gaurded by a unit of line infantry hiding in dense forest?

Defender vs attacker advantage is not so significant anymore either now with the introduction of all those artillery pieces.Are you still going to stand with your troops cowering on a hill while my artillery shoots a tremendous barage of cannonballs in your tight formations?
You will be forced to engage your troops in open field and exchange musket fire.

These are only a few examples of many situations that will occur in the battlefield, things will be much more balanced and i expect many honorable open field confrontations.These will be bloody and brutal battles but we will remain gentlemen in command to lead our armies to victory.

This makes me wonder however if officers are taken into account that as soon as one falls the unit will suffer a blow in morale?
