Watch disrespectful crowd get taught a lesson by guard at Arlington Cemetery (VIDEO)

America honors servicemen who made the ultimate sacrifice, a sentiment many families understand.

My oldest brother served nearly 24 years in the Army, with three deployments to Iraq. He formed strong bonds, especially with his friend Gary. Tragically, when my brother couldn’t accompany Gary on a supply run, Gary didn’t return. This loss deeply affected my brother, who visits Gary’s grave regularly and teaches his children to respect fallen soldiers.

While most attendees at memorials are respectful, some, as shown in the next video, are surprising. One of the highest honors is guarding the Tomb of the Unknown Soldier.
