Do as many things as you can to make each JBT say "WTF!?" I call these 'WTF factors.' The more WTF factors you can put in their way, the better. Not just conventional booby-traps, but things like manakins, silhouettes, or even posters in every room. See how many rounds they shoot off thinking that Lord of the Rings poster is a badguy. Put large mirrors on the walls so they see their own reflection and start firing. Put as much large heavy furniture in their way. Block doorways and windows with it. Create false 'last stand barricades.' Hang sheets and tarps from the ceiling to impair their vision. Rig up dummy explosives everywhere and create a spiderweb of "trip cords."
The whole purpose of the 'WTF factors' is to disrupt their SOP. They've trained and trained and trained to operate in a certain away, under certain assumptions. They're trained to operate hard and fast. If they keep getting slowed down by random unpredictable bullcrap in their way, they lose a lot of their momentum and confidence.
All the while they're stumbling around in your fun-house, you're safe and sound elsewhere.
On equipment: You get what you inspect, not what you expect. On training: Our drills are bloodless battles so that our battles are bloody drills. On tactics: Cheating just means you're serious about winning.
