Microphone Headsets…Peltor® No Longer Restricted

    Between November 2010 and May 2011, conventional Army units submitted more than 850 requisitions for the Peltor® COMTAC III™ microphone headset.  All the requisitions were rejected.

    The Army’s Rapid Equipping Force (REF) looked into the problem and here’s what they found: The source of supply (SOS) code for the headsets was F56.  That’s an SOS maintained and used only by Special Operations Forces.  That’s why requests from outside of special forces were rejected.

    REF succeeded in making the Peltor® headsets available to all Army units.  Now the Defense Logistics Agency (DLA) manages the headsets.  They carry an SOS code of SMS.

    Here’s what you can order:



Single or dual

communications channels

Color Push-to-talk (PTT)
7941 single olive drab Comes with one PTT.
7829 single coyote brown Comes with one PTT.
7946 dual olive drab Comes with two PTTs.
7797 dual coyote brown Comes with two PTTs.


    You can also order a spare boom microphone with NSN 5965-01-572-7803.

Food Sanitation Center…

    A food sanitation center (FSC) is all about heat.  Heated water.  Heat shields.  Thermometers and hot temperatures.  Here are a few tips for using your FSC correctly while avoiding burns:

              Heat Shields

    You’ll be using very hot water to wash, rinse and sanitize pots, pans and utensils.  That means the metal sinks will get hot.  Before you do anything else, install heat shields on the sinks so you won’t burn yourself.

Heat shield NSN 5340-01-541-
Front 4996
Coupler 4998
Edge 1917

    You need three front shields, two couplers and an edge.

                How Hot?

    The FSC comes with three sinks: one to wash, one to rinse and one to sanitize.  The water temperature in each sink is different.

Sink Temperature
Wash 110 to 120oF
Rinse 120 to 140oF
Sanitize 171oF or above (not 170oF as listed on the front shield)


    WP 0006-00 of TM 10-7360-211-13&P (Aug 06, w/Ch 2, Sep 10) spells out the temperatures.  You’ll find the TM on USAMC LOGSA’s Electronic Technical Manuals Online website:




    Para 4-43 of TB MED 530, Occupational and Environmental Health Food Sanitation, also lists the temperatures.  You’ll find the TB on the Army Publishing Directorate website:


Adjusting the Temperature

    Fill each sink with water to the —FULL— mark.  That’s about 7 1/2 inches deep.  Then push the metal stems of the thermometers, NSN 6685-00-444-6500, all the way down through the brackets, NSN 5340-01-333-8483.  Make sure the tips are submerged about 2 inches under water.

    Never start a modern burner unit (MBU) under a sink that’s not filled with water.  You’ll just heat the metal until it becomes burning hot.

    Next, fire up the MBUs.  Turn the burner controls for more or less heat.  Adjust them to reach and hold the required water temperatures.  Keep an eye on the thermometers.

    One more thing about the sinks: They arrive with clear tape over the drains.  Remove the tape before using the sinks.

    For the full story on the FSC, read your -13&P TM.

Advanced Combat Helmet

    Without a chin strap, your advanced combat helmet (ACH) will soon tumble off your head.  Get the Specialty Defense Systems (SDS) Warrior four-point chin strap with NSN 8470-01-530-0868.

    The NSN includes the strap and four each of the attachment tabs, mounting screws and posts.  The strap comes in a one-size-fits-all foliage green.

    NSN 8470-01-531-3351 gets the strap alone without hardware.

    Need to order the individual hardware—attachment tabs, mounting screws and posts—for the SDS Warrior strap?  FED LOG gives these items an acquisition advice code of V, terminal item.  That means the items are available, but only until the current stock is exhausted.  Here are the hardware NSNs:

Commo Batteries

    What Will You Do With This Power?

    Without batteries to power them, many of your radios and electronics are just lifeless heaps of metal, plastic and wire.  That’s why it pays to be battery smart.  Here are a few points to ponder:

    o Don’t hoard batteries.  If you’re the kind who usually stockpiles supplies, change your ways: Set a limit to the number of batteries you order.  Have enough on hand to fill your unit’s battery needs—no more, no less.

    You see, batteries need to be used in equipment.  Left lying around too long, they begin to lose their power.  So, rotate your stock.  First in, first out.

    o Determine your unit’s battery needs.  Use CECOM-LCMC’s Power Optimizer for the Warfighter’s Energy Requirements (POWER).  It’s a Microsoft® Excel-based application that helps you manage battery supplies.  Here’s what POWER can do:

    present battery options for your equipment

    figure out a battery’s run time based on surrounding temperature

    estimate how many batteries you need to support your mission

    Get POWER by emailing Ari Herman at CECOM-LCMC:


    o Stay out of the heat.  High temperatures drain the life out of batteries.  They cause the loss of capacity.  Capacity is the amount of energy a battery can deliver in a single discharge (normally expressed in ampere hours).

    Most commo batteries can withstand 110oF for a few days without harm.  But when the temperature reaches 130oF for more than a few days, any battery can be seriously degraded.

    So, keep batteries cool during storage to preserve their shelf-life.

Never store them in direct sunlight during hot weather.  Never store them in a closed, unventilated shelter, CONEX or MILVAN in the summer.  That’s when temperatures soar inside these containers.

    For ideas on how to keep batteries cool, read SB 11-6, Communications-Electronics Batteries Supply and Management Data (Feb 10).  You’ll find it on the USAMC Logistics Support Activity (LOGSA) Electronic Technical Manuals Online website:


    o Keep batteries in their original packaging while in storage.  The packaging:

    identifies batteries by stock number, lot number, manufacturer and type

    helps prevent damage from high humidity or dryness

    protects against crushing, puncturing and shorting

    contains battery leaks

    Take rechargeable batteries out of their original packaging and charge them.  Return them to their original packaging for long-term storage.  Charge the batteries once a year from then on.

    o Report battery failures—cracks, stains, bulges, odors or leaks—on a SF 368, Product Quality Deficiency Report.

    o Before you go on mission, make sure your batteries work.  Test them with a simple tester.  Or run a radio/equipment check like your TM says. If you have large quantities of the same battery with the same date codes, test a small sample to make sure your batteries have power.

    Here’s a tester in the Army supply system that tests a variety of batteries:

    MBT-MIL Multi-Battery Tester™, NSN 6625-01-494-9163, part # MBT-MIL.

    Here’s what it tests:

AN/GRM-122 Radio Test Set

       ESD Takes Out Circuit Cards

     Your AN/GRM-122 radio test set has three major components that contain circuit card assemblies (CCA):

    o TS-4317/GRM

    o J-4843A/GRM

    o PL-1536/GRM

    Before you handle any of the CCAs, consider this:

    CCAs are sensitive to electrostatic discharge (ESD).  ESD can degrade or destroy transistors, resistors and the integrated circuits of CCAs.  The discharge can happen while packaging, shipping, handling or installing CCAs.

    Where does ESD come from?  It comes from electrically charged objects all around you: clothing, rugs, chairs, papers, manuals, ordinary packaging materials or the work surface itself.

    But more than anywhere else, ESD comes from you.  Your body has thousands of volts of static electricity.  When you handle a CCA without proper grounding, that static electricity is discharged.  You may not feel the discharge or see the damage—but it’s there.

Protect Your AN/GRM-122 CCAs from ESD.

    o Make sure you’re grounded before you open the test set’s components and handle the CCAs.

    o Open the components and handle the CCAs only at a static-safe work station that includes a grounded table mat, floor mat and wrist strap.  They’re designed to limit static buildup and carry already existing charges to ground.

    o When you receive CCAs, make sure they’re in their original, unopened packages.  If they aren’t, the CCAs must be downgraded to supply condition code F, unserviceable.

    o If you return a CCA to the depot for any reason, make sure it’s packaged in an ESD-protective bag.  ESD-protective packaging is required no matter what condition the CCA is in.

    o When you store CCAs on shelves, work benches or in tool boxes, they must remain packaged.

    o When you open the packages, handle the CCAs only at a static-safe work station.

    Here are some available static-safe products:

Item NSN 5920-01-
Table mat, common point ground and wrist strap 250-4236
Portable work surface, common point ground and wrist strap 250-4237
