It feels really bad getting attacked in force march, but hey that's the price of moving your armies around right? What feels even worse is when your armies have been sitting in a settlement in force march for more than a turn and then get attacked. They're still tired, despite not having marched anywhere.

My idea is for a rather simple mod that modifies the force march stance so that if an army has not moved, it will grant an amount of experience at the end of turn. Army is still tired because they've been training hard.
