Some things for us to pay close attention to are the mistakes these JBT squads are making. Sometime its just a simple mistake as tripping on your partner's foot and you end up shooting him in the back by accident. Stupid little mistakes can end up turning into huge problems, especially with CQB. Study it and practice.


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.
