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.

To get your goggles fixed, you’ll need a return authorization number (RA#) 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 number, fill out a DD Form 1348-1A and ship the goggles to:

M326 Mortar Stowage Kit . . .Engaging Disengage Lever

The M326 mortar stowage kit (MSK) is used for transporting the 120mm mortar. When Soldiers have trouble moving the M326’s disengage lever on the gear box, they sometimes hit it with a blunt object like a hammer.

Bad move! That breaks the handle. The only fix is to replace the entire hydraulic drive.

To keep the lever from locking up, operators should quickly press the HOIST DOWN button on the control pendant assembly when the mortar is in the travel position. That releases pressure on the gears, allowing the disengage lever to move freely.

If power is lost and the gears are locked up, follow the procedures in WP 00 13 in TM 9-2590-527-13&P.

If you have any questions about the M326, contact Erik Jensen at (586) 282-1220 or email:

M1-Series Tanks…Screen Strains Debris

Mechanics, when you’re replacing the M1-series tank’s turret distribution valve (TDV), NSN 4820-01-308-1858, be sure to give the inlet strainer screen a good eyeballing.

TDV Screen

That little screen, NSN 4730-01-292-7776, protects the TDV from big problems caused by debris from the hydraulic reservoir. Using a clogged or damaged screen makes the TDV strain to do its job.

Make sure the screen isn’t damaged or blocked by debris. Clean it if needed or order a new screen if the old one’s no longer serviceable.

A new TDV doesn’t come with a screen, so you’ll need to order one separately. Never install a TDV without a screen. And it’s a good idea to keep a few extra screens in your tool truck.

Stryker… AFES Fire Bottles Make a Change

Crewmen, the fire extinguisher bottles for your Stryker’s automatic fire extinguishing system (AFES) are getting a makeover.

The crew compartment’s composite fire extinguisher bottles, NSN 4210-01-542-0008 for the Stryker and NSN 4210-01-600-8571 for the double V-hull Stryker, are being phased out. They’re being replaced by a steel version, NSN 4210-01-621-9540, that works for both the Stryker and double V-hull Stryker.

The engine compartment’s composite fire extinguisher bottle, NSN 4210-01-541-9993, for both the Stryker and double V-hull Stryker is also being replaced by a steel version, NSN 4210-01-503-1522.

You can still use the composite bottles as long as they’re serviceable.

AGSE . . . The ALUMMC is Coming Soon

Crews and mechanics, PM AGSE will soon be fielding the new aviation light utility mobile maintenance cart (ALUMMC), NSN 1740-01-632-9476. The ALUMMC is a flatbed cart and is designed to haul parts and equipment around the hangar and airfield.


As with any new vehicle, your priority is to make sure you perform all the PMCS listed in TM 1-1740-213-13&P. According to the maintenance allocation chart (MAC), operators should only inspect the ALUMMC. Mechanics (MOS 91B) perform all maintenance by the book, without taking shortcuts.


Here are a few tips you need to know about the ALUMMC:

o When loading the cart, the maximum payload capacity of the bed is 800 pounds.

o The ALUMMC is not intended to be used for towing. It may look like a rugged workhorse, but don’t let that fool you. Always use the standard aircraft towing system (SATS), NSN 1740-01-575-5662, to tow aircraft.

o The only jack authorized for use on the ALUMMC is the 5-ton hydraulic jack, NSN 4910-00-289-7233.

o The vehicle has a fan, ventilation system and a heater, but no air conditioning. To keep it cool, remove the doors like it says in WP 0129 in the -13&P TM.

Take some time to read through the new TM and familiarize yourself with it. It’s your guide to maintaining the ALUMMC. The new vehicle has a 24 month or 2,000 hour warranty, whichever comes first. If you have any issues outside of normal wear and tear, contact PM AGSE to determine warranty applicability.

New Tourniquet Available

The US Army Medical Materiel Agency (USAMMA) is fielding a new junctional tourniquet designed to save warfighters who are injured in the groin or armpit areas.

The SAM® junctional tourniquet weighs about one pound. It straps on like a belt and includes two inflatable air bladders that medics can inflate individually or at the same time. It can be positioned in less than a minute—a critical advantage for combat medics who often just have mere minutes to save a life.

The Combat Application Tourniquet is still standard issue to all deploying Soldiers, but it doesn’t work on junctional injuries.

A junctional tourniquet modular lightweight load-carrying equipment

(MOLLE) bag has also been developed that fastens to a combat medic’s main M9 bag.

Get the new junctional tourniquet and MOLLE bag with NSN 6515-01-646-2617 (about $500), or order the tourniquet

alone with NSN 6515-01-618-7475 (about $300).

Each single-use tourniquet comes with a training DVD and step-by-step instructions printed on the actual device, plus an instruction card.
