I'm already playing the first scenario in Spearhead. It has a number of distinguishing features imo that make it unlike any other scenario I've played. This is great to see. The battle scenario arrangement shines in this pack as well. This is quickly shaping up to be my favorite module in the whole line.
I'll try to write up a full AAR for the scenario database when I'm done.
Fwiw I'm partial to the M4 defense revision (upping the armor from 3 to 4), so I think I'll play with that from now on. The Spearhead pieces of course still use the original 3 defense.
The first scenario also features the US 1st infantry, the Big Red One. Were there ever Big Red One counters published? All I could find is an old pdf of the Texas division (the 36th).
