Just thought Id show you guys a little of what I do. Like iv mentioned before, I'm a Vehicle tech for the Canadian ARmy. I snapped some photos of me and my Crew pull a pack on a LAV 3. Takes us about 45 mins to pull it and once all repairs are complete it take about 45 mins to drop it back in. In the one picture you see one of my Guys kneeling on top of the engine checking the Tranny fluid. And yes the Pack is running. One of our perks is having the ability to run up a power pack will its out of the Vehicle. Enjoy
