I was reading one of my Osprey books, Mustang Aces of the 8th Air Force, and I came across a quote by Kit Carson of the 357th FG that said "We don't use tracer as it gives a false sense of distance and direction, but when the steel cores hit home, they strike sparks which appear as winking lights so you'll know you're scoring." I was just curious about tracer policy in the 8th and if the decision to use them or not was on a group to group, or even squadron to squadron basis, or if this was throughout the whole 8th. Thanks in advance.
