Months after the backward rifle scope controversy, the commander of a Navy warship was relieved of duty.

It was a surprise that the U.S. Navy fired the captain of the guided-missile cruiser USS John McCain. About four months after a shot of Commander Cameron Yaste firing a gun with the scope on the wrong way around was widely criticized, he was fired. The event got a lot of notice and jokes on social media, which made people look closely at the Navy.

The picture, which was first posted on the Navy’s official social media accounts, showed Yaste in a shooting position with the scope mounted incorrectly. Many people online made fun of the mistake, so it wasn’t missed. The Marine Corps even joined in. They posted a picture on social media with the phrase “Clear Sight Picture,” which was a subtle dig at the Navy’s mistake. The original post with Yaste was quickly taken down, and the Navy admitted they were wrong by saying, “Thank you for pointing out our rifle scope error in the previous post.” The picture has been taken down until the EMI (extra military instruction) is over.

The Navy said that they fired Yaste because they “lost confidence in his ability to command.” But they didn’t say anything else about whether the rifle scope event was the direct reason. The USS John McCain is currently stationed in the Gulf of Oman to assist the USS Theodore Roosevelt, an aircraft carrier based in San Diego. Yaste’s removal comes at a very important time.

As a temporary measure, Capt. Allison Christy, who is the deputy commodore of Destroyer Squadron 21, has been put in charge of the USS John McCain. The Pentagon sent these ships to the Middle East as a safety step to make sure they are ready to help Israel if things get worse between it and Iran or other enemies.

When it comes to military actions, where even small mistakes can have big effects, this event shows how important accuracy and leadership are.
