When you bore sight
the main gun of a tank it dialing in the actual direction the main gun tube is
aiming and the targeting lasers that the tank uses. To do this you use a laser which literally
gets mounted into the gun tube of the tank, so the gunner can adjust his gun
sights to the spot on a giant white target created by the laser in the
gun. What the gunner sees all day while
doing this exercise is a red dot on a white back ground when they hit the
button on the targeting laser.
PFC Houlk, who is probably still in the service, and probably still a PFC, Private First Class. There is a particular type of soldier which will attain this rank and never get past that point their entire time in the service due to continuous minor infractions of assorted sorts.
Anybody who was ever in the service will remember these troublesome but hilarious people, because they are the comic relief for a way too serious Army, or whatever branch of service you happened to be in. PFC Houlk, had managed without being noticed to not only get these many bags of flashlight lens covers out to the gun range, but had ran around the target area emptying the contents of the bags before we started bore sighting with a new group of lieutenants.
