@OutisWalking on top of walls along their extent while being a bit protected could indeed be an interesting side-effect. Which brings me to a (most likely stupid) question: A soldier positioned on a wall has some protection against enemy fire. I the same soldier is behin that wall, does he have the same level of pretection, more protection, or less protection?  From my simple mind I would guess being behind a wall shoudl provide more protection. Most likely implemented as expected. Can anyone confirm, please?  

Yeah I've updated the scripts and ported that mod to test. I need to publish 28.1 on mod.io

That looks very well

I use formations only to group my army better before the attack. Note that there are some serious bugs with formations. If you add an unit that is very far away, the entire formation stops and waits for that unit to get near. Also, if you attack move with the formation active, only some of your units will move in to attack.

About formations, I almost never use them because when you order your soldiers to attack the formation automatically disbands, no matter how far away the enemy is. It would be nice to either: A: make it so that formations must be manually disbanded, otherwise they fight in formation (at least some formations should work like this, like the Phalanx) B: units stay in formation until an enemy is in sight, then they disband (not historically accurate for most formations, like the Phalanx).
