From a previous discussion revealed by old guard alum:
“The Old Guard’s Presidential Salute Battery conducts rehearsals (aka Blank-Fire Crew Drills) on Thursday mornings starting at 0700 in Arlington National Cemetery and on Ft. Myer. These drills are used to rehearse for upcoming ceremonies and certify new Soldiers on the ceremonial 105mm howitzer cannons. They do the drills before the cemetery opens for the day. The modified howitzers can only fire blank rounds; no projectiles.
During changes in the seasons (usually late spring or early fall), the sound from the blank shots tends to travel further and more residents hear it. Not sure if it has something to do with the changing temp… foliage…?”
I know it’s not Thursday but this is still my guess.
Doug also notes: “So this has to be the answer, the cadence is def cannon-salute-esque
Gotta be some sort of weather/atmospheric situation this am that’s making the noise carry more than usual though”
