This video above makes some very similar points that Derek Johnson has made over the last few months regarding Uniform Code of Military Justice or military law which is different to constitutional law.

Trump received a full grade military and constitutionaly regulated inauguration ceremony including playing 'Hail to the Chief and a 21 gun salute (with five guns) on Jan 20th 2021.

Biden received a full grade military regulation funeral service including a procession to the tomb of the unknown soldier, and firing thirteen rounds with three guns. A three volley salute two guns for firing and one gun for misfires, is used for military funerals only. Thirteen rounds fires have three categories: 1.) Marine Generals and 2.) Rear Admiral. Joe bidden wasn't in the Navy, Marines or the Army.

The only other category where thirteen rounds are fired is 3.) Minister Resident. The definition of Minister Resident is a person who takes up temporary residence in a foreign territory. Hail to the Chief was not played for Joe biden instead Honours March One was played.

Regarding the uniforms, Derck Johnson says all of the uniforms around Biden on the 20th Jan 2021 were non regulation military uniform,meaning Hollywood could've done a better job that day. In the military uniforms are sacred because people have died wearing that uniform.
