The leader of the humans is willing to store arms in a temple that the occupiers have respected as a place of religion. He is also willing to wage war near the sick and the injured and willing to send men off to commit suicide in battle.
The leaders of the Czech resistance based themselves in a church and fought to the death within its walls. The Doolittle raid over Tokyo was a suicide mission, as were many other commando raids -- Remember The Bridge over the river Kwai. Any battle that lasted over a day was waged near the sick and the injured. War is called Hell for a good reason.
