Rock on with rocket help!
Suspect the contacts. If you load rockets in the launcher, but rockets aren't registering as being loaded, suspect the contacts. Before you spend a lot of time troubleshooting, first try cleaning the contacts in the tubes where the rockets aren't registering. If the contacts are dirty, the rocket doesn't have a good electrical connection, which prevents the launcher from knowing the rocket is loaded.

Rockets not registering? Clean contacts
Mark bad tubes. If troubleshooting does turn up a bad tube, mark out its number immediately on the top of the launcher at each end. That way you will remember which tube is bad and will know not to bother loading a rocket in it again.
Tube bad? Mark out its number of launcher.
Clean with clean bore brush. It is important to clean out the tubes with CLP and a bore brush. Otherwise, dirt and carbon can cause the rockets to jam. But your cleaning won't do much good if you clean with a dirty bore brush. That just spreads the gunk around. When the brush gets coated with dirt and carbon, give it a good cleaning with soap and water. Let the brush completely dry before using it again.
Use rocket loading tool. Use the tool, NSN 1005-01-536-7961, for loading and unloading rockets. Without the tool, you could jam the rocket in its tube against the rocket stop. Then, when you move the rocket forward to lock it in place, the end shield may be punctured and the igniter wire and weather seal may be damaged. That makes the rocket unusable because of possible exposure to electrostatic discharge and the hazard of electromagnetic radiation (EMR) to ammo and rockets.

If you do damage an end shield, contact your ammo logistics/quality assurance representative or turn in the rocket to the ammo supply point. You're not authorized to replace end shields.
