[Milisource] Presidential Salute Battery Fires Cannon Salutes During Trump's Inauguration

https://www.youtube.com/watch?v=J8WgrN7dVGQ&t=299s (4-gun battery, 3-second intervals)

First gun at timestamp 5:04 (+304 seconds): https://youtu.be/J8WgrN7dVGQ?t=304s

Last gun at timestamp 6:04 (+364 seconds): https://youtu.be/J8WgrN7dVGQ?t=364s

As is standard for the legitimate sitting president, he gets a 3-second interval.

Math:

Duration of interval

= |[Time of last shot] - [Time of first shot]| / [Number of intervals]

= |364 seconds - 304 seconds| / 20 intervals

= |60 seconds| / 20 intervals

= 3 seconds per interval

https://youtu.be/-jtdQGYLD0k?t=350s (3-gun battery, 9-second intervals)

First gun at timestamp 6:00 (+360 seconds): https://youtu.be/-jtdQGYLD0k?t=360s

Last gun at timestamp 9:00 (+540 seconds): https://youtu.be/-jtdQGYLD0k?t=540s

Math:

Duration of interval

= |[Time of last shot] - [Time of first shot]| / [Number of intervals]

= |540 seconds - 360 seconds| / 20 intervals

= |180 seconds| / 20 intervals

= 9 seconds per interval

9-second intervals are what is specified for a foreign dignitary in army regulations.

Foreign dignitary to Arlington:

Battery Commander's Orders are precise and deliberate

The battery commander specifies, vocally, the number of guns to be fired and the precise intervals to be used. At timestamp 0:20, pay attention to the battery commander's orders.

"19-gun salute, 9 seconds."

The salute begins about one minute later and is carried out precisely by all the personnel of the battery: 19 guns, 9-second intervals.

The video depicts a rare 19-gun salute (the title and description of the video is in error) in honor of the visitation of the Tomb of the Unknown Soldier by the Defense Secretary of Jordan. Note the number of artillery guns (3), long interval and on-path positioning.

This is a good indication that the Biden Administration is a foreign occupier on U.S. soil
