Many good points above, however, I still feel a Command set first is the bait on the hook and the way to go for the Alamo theme. And I had the same thought as Arlin - Have both Alamo Defenders & Santa Anna's Generals in the same set - 1 sprew of each. The 3rd sprew always is of the accompanying horses. We should get more 1812 militia and frontiersmen for the War of 1812 anyway.
I'd hope for the Defenders in Dark Gray and Mexicans in Blue, or both just in Dark Gray.
