🧵 Am updating once more my PLA Navy type & age structure graphs. Been doing these occasionally since ca. 2010 as they help me keep a grip on #PLAN fleet development; perhaps others find them useful too.

Starting this new round with the aircraft carriers. Let me know in case of typos/mistakes pls!

Further premeditated, lawless killing in the Caribbean.

Making at least five such US strikes.

Against unidentified "narcoterrorists" affiliated w/ an unspecified "designated terrorist organization" allegedly trafficking unspecified narcotics.

POTUS is asserting a license to kill outside the law.
Under my Standing Authorities as Commander-in-Chief, this morning, the Secretary of War, ordered a lethal kinetic strike on a vessel affiliated with a Designated Terrorist Organization (DTO) conducting narcotrafficking in the USSOUTHCOM area of responsibility — just off the Coast of Venezuela. Intelligence confirmed the vessel was trafficking narcotics, was associated with illicit narcoterrorist networks, and was transiting along a known DTO route. The strike was conducted in International Waters, and six male narcoterrorists aboard the vessel were killed in the strike. No U.S. Forces were harmed. Thank you for your attention to this matter!!!!!!

Green column: Russia

Touché.

If I remember correctly, this was one of the first scientific studies I saw in the open domain on distributed acoustic sensing with fiber optic cables being demonstrated, it's from 2022 and has a nice illustration of the concept

Finde den Fehler: Die #Bundeswehr soll bis 2030 stark aufwachsen; ihre #Militärlogistik ebenso. Doch die Bahnlogistik will bis Ende der Dekade ihr Personal von 17.000 auf 10.000 Arbeitskräfte abschmelzen.
