The U.S. Marines appeared to fire a shot across the bow of the U.S. Navy on social media Wednesday — a day after the latter posted an image of a man shooting a rifle with the scope mounted backward.

Technically under the Department of the Navy, America’s Marines are known to be a proud bunch.

Like other benches of the armed forces, they have historically enjoyed centuries-long rivalries with airmen, sailors and soldiers from other wings of America’s military.

That is why a Wednesday post from the Corps on the social media platform X had many people laughing at the Navy’s expense.

The branch shared an image of a Marine shooting a rifle aboard a Navy ship and pointed out it was a “Clear Sight Picture.”

“#Marines assigned to the @15thMEUOfficial conduct a live-fire deck shoot aboard the @usnavy amphibious assault ship USS Boxer, April 6,” the Marines posted.

“The 15th MEU is currently embarked aboard the Boxer Amphibious Ready Group conducting routine operations.”

The image clearly shows the optics on the weapon were where they were supposed to be.

In contrast, a U.S. Navy Instagram post from earlier this week that was later deleted showed a serviceman firing a rifle on the high seas, but it was noted his scope had been mounted backward.

“Highlighting the amazing work of our U.S. Navy Sailors!” the Navy wrote. “From engaging in practice gun shoots, conducting maintenance, testing fuel purity, and participating in sea and anchor details, the #USNavy is always ready to serve and protect.”

The image received its fair share of monkey online, including from Republican Rep. Mike Collins of Georgia:

Many who saw the Marines’ post made a connection between the two images:

The Navy commented Wednesday about its decision to delete the Instagram post when it wrote, “Thank you for pointing out our rifle scope error in the previous post.”
