Hey, that's cool. We had the added requirements of extreme stability during flight to stabilize the turret to allow accurate "pointing" during lasing. These optics guys are wizards with this stuff. The tolerances and stability they required was amazing. But then again, you can imagine what even .1 degrees of tilt at 10 miles would do to your accuracy (you'd be about 92 ft off your target). That drove some complexities into my design, needless to say.
