Hello my fellow patriots. I know this is something that seems to be accepted but I saw some debate about it earlier today. I have done research on this and came across this website and the person has done some really great research on it and provides a sufficient amount of evidence and references: https://write-aholic.com/why-didnt-biden-get-a-presidential-battery-salute/

Biden did not receive a Presidential 21-gun salute.

From my own findings here is what I found that I didn't see in the article above: During ceremonies, the platoon fires 3-inch antitank guns mounted on a 105-mm howitzer chassis. Three-man crews, consisting of a watchman (time keeper), loader and gunner, fire at intervals from three to eight seconds, depending on the type of ceremony. from: https://home.army.mil/jbmhh/index.php/teamJBMHH/units-tenants/TOG/presidential-salute-battery

Only two were fired for Biden. The intervals were not 3-8 seconds. That was not a standard Presidential 21 Gun Salute.
