28. I was a tanker on the M1-Abrams-series tanks.

The first model of M1, with the old 105mm gun, the turret interior lights were white light, but with the flip of a switch, you could change them to red light, preserving night vision for operations after dark.

When the newer M1A1 Abrams went into service, they ditched the changeable interior lights to a constant light electric-blue; don't know why. We all hated it.
