Been reading Hoplites at War by Paul Bardunias and started reading about Greek phalanxes and field works. Apparently Cleomenes used cut down trees, Corinthian city walls, and ditches to bolster his flanks. This was also possibly done at Marathon to keep the Persian Cav at bay
So how about this for a house rule: You can switch out any element in your army with a thin line of Field works up to a maximum of 3. Perhaps represented by a row of pipe cleaner. Counts as bad going when crossing
Elements can fight behind it when charged, and enemy count as overlapped when attacking across it. It cannot move but does not count as an element lost when lost. You still have to deploy it outside of 3BW from the center line but you can put it all the way out on the wings as light troops and Cav. Enemy must conform to fight across it.
What do you guys think?
Another option would be to have a 40x40 element of bad going that you can plunk down anywhere in your deployment zone. Would affect you as well as the enemy.
