If you can't see it you can't shoot it.

To help the 7th Inf. DivArty see in the dark, the 7th FA Searchlight Platoon is always ready to throw some light on the situation.

The platoon has a lot of light to throw, too. The giant 60-inch searchlights, mounted on 2½-ton trucks, are rated at eight million candlepower.

At pencil beam, they can throw a shaft of light 20,000 yards and burn steadily for an hour and 45 minutes before their carbon arcs sputter out. They can be replaced in three to four minutes.

The platoon has a variety of jobs - it may be assigned the tactical mission of general support, director support or a combination of the two. It may be attached by platoon, or any of the six individual sections may be attached to another unit or assigned an illumination mission.

The 7th FA Searchlight Platoon was organized in March, 1955.
