Fine wind-blown dust is the curse of every Soldier serving in the field. Dust blankets equipment and settles into openings big and small.

Allowed to do its dirty work, dust will jam your weapon, choke your vehicle’s air filter and overheat your commo. So if dust gets into your modern burner unit (MBU), it could extinguish the flame and…that spells the end of hot chow.
For the sake of fine dining, take a stand against dust. Heed these tips for keeping your MBU clean…
  • Place the MBU with the control panel facing into the wind. The panel helps to block wind-blown dust from getting inside.

  • Make sure fuel cans are tightly capped. That keeps dust from contaminating the fuel.

  • After using the MBU, inspect the air filter, NSN 7310-01-462-4913, on the fuel delivery block. Replace the air filter if it’s dirty. Keep spare filters on hand. Clean the fuel nozzle whenever you change the air filter.
