Watch Out for Bulging Tubes

Watch Out for Bulging Tubes

Crewmen, it’s bad enough when explosive ordnance disposal (EOD) has to remove a stuck round from your 155mm howitzer. It’s a lot worse if you’re left with a bulging cannon tube!
That’s what could happen to your howitzer if EOD uses the water blast method to remove a stuck round.   The 155mm cannon tubes most at risk are the M7776 and M284 steel and M7776 and M284A2 chrome barrels.

If EOD uses the water blast method to extract a stuck round from your howitzer, inspect the cannon tube with a borescope. A bulge means the tube has to be condemned. If you suspect a bulge but can’t see one, use a pullover gage to measure the area where you suspect damage.
You’ll find the full scoop on inspecting for damage in TM 9-1000-202-14, Evaluation of Cannon Tubes. Appendix T covers the M7776 tube and Appendix U covers the M284 tube. EM 0065, which covers most small arms, has the TM, as does LOGSA’s ETM website:

Be sure to immediately notify your logistics assistance representative (LAR) or field service representative (FSR) if EOD removes a stuck round from your howitzer.
You are also required to report EOD round removal and any damage on DA Form 2408-4, Weapons Record Data Card, in the remarks column. You can access it at:


AN/PSQ-20/20A Goggles Blind? Good News!

If your AN/PSQ-20, NSN 5855-01-534-6449, or AN/PSQ-20A, NSN 5855-01-603-0489, night vision goggles aren’t working, there’s good news. You can get them fixed if they qualify.

The fix doesn’t cover ancillary items or components of end item for the goggles and is available only if the goggles fail after a thorough inspection following TM 11-5855-322-10 or TM 11-5855-335-10 or their -23&Ps. Your 94F repairman does that.

To get your goggles fixed, you’ll need a return authorization from the manufacturer. Get it by logging into the warranty repair portal:

New users will need to register by clicking on the HERE button on the left side of the web page. Returning users can log on with their email address, password and DODAAC.

Once you receive a return authorization, fill out a DD Form 1348-1A and ship the goggles to:

Test Set Ensures Clear Vision

Many arms rooms already have a device that makes sure night vision devices, weapon sights, and driver’s viewers work properly.

The TS-4348/UV provides a near- infrared uniformly illuminated target that shows if night vision goggles meet the high and low light resolution requirements called for in the TMs.

Unfortunately, most TS-4348/UVs sit because no one knows how to use them. As a result, night vision or sight problems aren’t spotted until Soldiers go to the field.

To learn how to use the TS-4348/UV, see TM 11-5855-299-12&P.

If your unit doesn’t have a TS-4348/UV, order it with NSN 6625-01-323-9584 for around $1,700.

Remember, to be accurate, the TS-4348/UV must be calibrated. Check its TMDE calibration label to see when it’s due. No label? Send it to TMDE for calibration.

3 Tips for Getting PS Back Issues

We get lots of requests for PS back issues. That’s great! But we also get returns from the post office after filling back issue requests. That’s not so great and it’s costly, too.

Here are some tips to help make sure those back issues reach you:

Give us a good mailing address. Most returns are due to incomplete or inaccurate mailing addresses. Including a street with the address is critical. If you have any problems with mail reaching you at your military address, use your home address instead. No worries—our mailing list is never sold or shared.

We’ve gotten “refused” returns, too. Make sure that you tell whoever usually gets the mail at your unit that you’re expecting a package from PS. In your original request, specify the months or years and how many copies of each PS issue you want. Send your back issue request to:

You can also request back issues by clicking on the REQUEST BACK ISSUE button at our website:   Just scroll down to the bottom of the tan-colored column.     To set up a monthly subscription to PS, follow the instructions at: can always download PS in digital form from our website, too.

PS Mobile App

You can also load recent issues of the magazine to your mobile device by using the PS Magazine mobile app. Read about it at:

PS supports the concept that you meet inspection requirements of having three years of PS Magazine on hand if you have them in either print or on your mobile device. Access means accessibility, not print vs mobile format.

Demil Lasers and Sensors

Because the following sensors and lasers will no longer be sold to the public due to a Class II laser exemption, their demil codes are being changed from F to D.

That means you can demil them without having to contact TACOM. Break the glass on all of them, including each of the lasers, and remove their batteries before turning them in to DLA Disposition Services.
