Assuming date of video is correct - today 09 Mar 2021 - the motorcade: https://youtu.be/fy-jpV6D7cE
Direction motorcade was traveling at POV of source - the arrow indicates both area of POV and direction of travel: https://files.catbox.moe/lg8a1m.GIF
Xiden motorcade looked to be heading out of the city. Certainly the wrong direction in relation of White House to WS Jenks Hardware in NE - where Xiden traveled to today: https://files.catbox.moe/ptg6ii.GIF
The HMX helos I have no idea where they were coming from. Looked to be from VA side, not JBAB.
Nice, thanks for the info. I’m from southern Maryland and life in northern VA now. I never knew the marines were in DC at all.
Good friend of mine served there for 23 years in the band. All ceremonial.
