One more thing I wanna mention about the Militia card is, that guerrilla warfare (in real life) is not built around traps. Yeah sure, if the enemy gets into their controlled territory tunnels and other traps are commonly used. But the essence of guerrillas are hit-and-run strategies, to debilitate the enemy when they are weak, and to take their arsenal for themselves as the only stuff they can make themselves is homemade weapons.
