Agreed. Another issue specifically if we use traps to set it up is it will take time to set them up no matter how good someone is. Time and material, though material I would be less worried about since it'd be found around the ruins where the troops were. Time is the most worry. 

That being said Regina would gladly volunteer to hold it's attention, not that that's the best decision considering her intimate knowledge of traps and focus on guerrilla warfare.
