The Harlem Hellfighters of WW1 fame were deployed as the 369th Coast Artillery Regiment (15th New York) in WW2.

Their service in WW2 was not only heroic, it was strategically vital...and their treatment that time was the forgetting of both.

1/
In 1943 the Harlem Hellfighters 369th regiment was broken up and organized into the 369th Anti-Aircraft Artillery Gun Battalion and the 870th Anti-Aircraft Artillery Automatic Weapons Battalion.

The African American 870th AAA AW Btn was shipped to Okinawa, Lt. Col. W. F. Lucas commanding.

The 870th was to guard one of the airfields to be built in Southern Okinawa after the island was over run at the end of Apr 1945.

The IJA & May rains put an end to that plan.

870th AAA AW Btn was armed with 16 each 40m autocannons and M-51 quad-Maxon mount .50 caliber machine guns in four batteries with four of each weapons.

When the 870th Harlem Hellfighters arrived at Okinawa. Their 40mm and .50 caliber weapons were taken away from them. They were issued rifles, carbines, machine guns, bazookas and mortars and sent to Kerama Retto.

The group of islands was a major Naval base with a problem.

The problem was that the islands in the group had not been properly cleared of Japanese resistance by the assault troops.

While more than 350 IJA suicide boats were captured or destroyed at Kerama Retto. When the 77th Division infantry battalion was withdrawn. The garrison

...crewing them came out to contest American control of Kerama Retto.

On 11 May a landing party lead by USN Cmdr Drexler, the C.O. of LST Flotilla 47 went to Aka Shima and was ambushed by hold out Japanese soldiers.

Drexler's bayonetted body was recovered the next day.

Midnight 11/12 May a Japanese infantry force assaulted Tokashiki town with rifles, Bangalore torpedo's and satchel charges

On the 16 May 1945 at Zamami Shima a USMC SCR-270 radar fuel was set on fire by infiltrators.

The ensuing fire badly burned 3 officers and 31 enlisted.

With all of this going on, the 870th was converted to infantry to mop up the Japanese the 77th Infantry Division left behind.

This is a short description of their work from the late 1945 report Antiaircraft Activities of the Pacific War.

This is the Tenth Army After Action report Anti-aircraft Staff Section describing the 870th's infantry work in Kerama Retto.

And this is the description of the 870th's infantry work in the article "Activities of the Tenth Army AAA," Anti-Aircraft Journal July-Aug 1949. See the passage from Pages 9 - 10 below.

This map of the US Navy seaplane sectors searched from Kerama Retto gives you an idea of how vital the work of "Harlem's Hellfighters" was in securing the island group was in WW2...and how little recognized.

Russia faces a logistical dilemma in occupied Ukraine for which it has no good solutions.

Crimea is a de facto island fed by road and rail bridges Ukraine can now destroy at will, and Russia cannot stop.

And Ukraine is destroying those bridges.

1/ Image
Russia's air defense has suffered a nearly complete "Lanchester Square Collapse" proximate with the Ukrainian mass deployment of both 150 km range AI truck hunting drones and bridge busting FP-2 OWA drones.

Any route Russian trucks take to Crimea will result in parking lots near replacement pontoon bridging for both those kinds of drones to exploit.

"Trucks that mass together...die together.

Saving Space Access From Kessler Syndrome

Elon Musk’s plan for XAI satellite data centers, and all use of space for any purpose, faces inevitable collapse until a solution emerges for the problem of Kessler Syndrome (see Wikipedia). 🧵

1/
This will occur when enough collisions of small orbital debris pieces from old dead satellites hits the steadily increasing number of new satellites until the whole thing spirals into mass collisions.

Kessler Syndrome computes that this will destroy all existing

...communications, navigation, observation and research satellites in low/medium orbit, and prevent all further satellites launched, for 40+ years, until enough pieces fall out of orbit into the Earth’s atmosphere.

Do you remember all the 2023 US Navalist accounts o X that screamed at @johnkonrad and I about pointing out the containerized anti-ship OWA drone threat to the US fleet.

Welcome to 2026 Ukrainian anti-ship OWA drone threat, you US Navalist yo-yo's. ⬇️

"Operation Spiderweb with Chinese characteristics" is coming for you all, and we have the receipts.

We need a whole lot of air defense guns everywhere to stop drones that you guys still refuse to fund.

For fun and reference of guns versus missile air defense, this YouTube test scenario pits 100 Shahed-136 one-way attack drones against the historic US Navy Task Force 38.1 from 1944.

Just...no. The 8th AF fudged its accuracy numbers.

It excluded "gross error" bombing runs beyond 3,000 feet from the target. Which were above 10% of all 1944 bombing runs.

Below, the inner circle is what a 1944 1,000 foot (304m) CEP in WW2 looked like when dropped from 400(+) four engine heavy bombers.

Using this document:

THE UNITED STATES STRATEGIC BOMBING SURVEY
Bombing Accuracy, USAAF Heavy and Medium Bombers in the ETO
MILITARY ANALYSIS DIVISION
First Edition 3 November 1945
Second Edition January 1947

You find both mission failures & gross errors were "excluded data"

And that both increased altitude and the number of combat boxes involved made CEP worse.

There are sound photographic reasons I'm talking about Russia's domestic fuel tanker supply distribution chain breaking down.

Dead tanker trucks can't move fuel.

Plus additional tanker trucks diverted & moving from 🇷🇺 to 🇺🇦 can't deliver fuel domestically either.

For additional photographic proof of 🇷🇺 tanker truck supply distribution breaking down, see here in Belgorod:

This manpower sweep problem is actually a lot worse for the Russians than Western military intelligence is capable of giving credit.

It takes a Russian labor gang about 3 hours to load 16 tons of wooden boxes w/o a convenient box car to truck line up. (below upper right)

Because the Russian Army doesn't use pallets, forklifts, telehandlers nor D-rings anywhere in their supply chain to strap down pallet loads.

You need massive numbers of conscripts to load and unload from train cars to trucks & vice versa.

This has a whole lot of knock on effects in how the non-mechanized Russian supply system works in the age of GMLRS & drones.

You see here a commercial to tactical truck swap of wooden boxes in the Russian Army operational/strategic depths.
