Enjoying this a lot.
I understand that forces that enter a battle on different chit draws fight at different times. The first troops to engage in battle are "Front Line" with later "reinforcements" starting in the reserves. No problem there. Clean system, works well.
What about forces that enter on the SAME chit draw, but from different directions? Are they all "Front Line"? This is particularly relevant to breaking out of encirclements, when the escaping force is being aided by a relieving force (or, in the case I am looking at, 3 relieving forces)
