However, it turned up some new situations that needed resolving with regards to field fortifications and I need to log the following amendments.
Units assaulting or crossing earth entrenchments/field fortifications do not get their melee multipliers and move at speed 2. This applies until the unit has completely cleared the obstacle. Units defending do get their melee multipliers if applicable and if they have passed any necessary morale checks.
Artillery defending entrenchments have a 45 degree firing angle.
