The KGV-72 programmable in-line encryption device (PIED), NSN 5810-01-546-3364 (LIN E05008), is designed to encrypt Blue Force Tracking (BFT) message traffic. But when it’s time to turn in the PIED, here’s a message that really needs to get through:
Don’t damage the locking block!
Too many units are losing or misplacing the padlock key. So when it’s time to turn in the PIED, they use tools to remove the lock. Unfortunately, that almost always breaks the locking block.
A broken block can’t be repaired. Even worse, you can be held financially liable for replacing the $2,565.58 PIED per AR 735-5, Property Accountability Procedures and Financial Liability Officer’s Guide. A DD Form 200, Financial Liability Investigation of Property Loss (FLIPL), along with a property book officer document number must be submitted at the time of the request to the item manager before an operational PIED can be issued.
So don’t lose the key to your lock. And if you do, check with the item manager for instructions on what to do next.
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:
On Page 43 of PS 760 (Mar 16) we told you the good news that the M205 tripod is replacing the M3 tripod.
It’s good news because the M205 is 32 percent lighter than the M3 and also includes an integral traverse and elevating mechanism.
But some units are jumping the gun and turning in their M3s before they get the M205. Not a good idea! They could be without tripods for a long time until they do get the M205. So keep using your M3s until you get the M205.
But once you get the M205, it’s important you turn in your M3s within 30 days. The Army will continue to use M3s for 3-4 years, so they need your M3s for other units. If any M3s aren’t usable, turn them in for local disposal.
Do not try to order the M205. If will be fielded through total package fielding (TPF).

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:

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.
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:

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.
Mechanics, the final drive hub sprocket’s threaded bolt holes on your M88A1 can strip or even break if you don’t do PM. That could leave your vehicle with a wobbly final drive sprocket.
Here’s how to keep those bolt holes in good shape and your final drive sprocket on track:
- During semi-annual PMCS, inspect the final drive hub bolts. Re-torque loose bolts, NSN 5306-00-799-7722, to 225-250 lb-ft. Locking nuts, NSN 5310-00-225-6408 should be torqued to 70-90 lb-ft.
- Only use those locking nuts once. If they’re loose or have to be removed, replace ‘em.
- Always use a dab of GAA on the final drive hub sprocket bolts and locking nuts during installation.
