1776 on the other hand sacrifices playability to give a good 'feel' for a battle at this level, as well as a fair amount of choice as to how the battle is to be fought. Various assorted esoteria also surface in both games with regard to combat. AR does not give entrenchments a wide utility while 1776 tends to make both forts and entrenchments less effective, especially when artillery is handy for the side assaulting a fort or earthwork. Artillery is unique to 1776. It is slow and often gets left behind since its only use is in attacking forts and earthworks.
Supply is the next point to be raised.
1776 has supply units. They have, however, the same movement allowance as combat units of the respective side. They may not however force march. Combat is possible without them, at half strength, and no continued combat is allowed. Supply units are used up by continued combat, but replacements are fairly plentiful.
