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 When the 77th Division infantry battalion was withdrawn.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.

8/ Image
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.

10/ ImageImage
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.

Oh My!

The electromagnetic compatibility (EMC) of these jammer mountings has got to suck.

How many "nulls" this jammer throws (AKA where no jamming energy transmits) will be substantial.

1/
I did a thread on this in 2024 when the first turtle tank jammers appeared.

2/
The basics of electromagnetic compatibility (EMC) studies of antenna mounting have been around since 1944.

This is a development I have been expecting, once the AI truck hunting drones started hitting the main roads in occupied Ukraine.

Mining roads by air & rocket was late Cold War NATO doctrine after all.

1/
Deploying lots of anti-tank and anti-personnel land mines with Gator cluster munitions dispensers was one of the major themes of the 1980's Follow On Forces Attack (FOFA) doctrine.

The doctrine was highly effective, hence Ukraine using it in 2026.

2/
Image
The major issue with Gator is it ran a fowl the never sufficiently cursed out Ottawa Treaty banning AP land mines.

Despite the USA never having signing the treaty.

It generates international NGO lawfare accusations of "War Crimes" every time the USA uses the munition.

Regarding this:

>>The intensification of strikes against Russian 🇷🇺 logistics (150 vehicles, 30 trains, 400 warehouses) is a real game-changer in the war.

The 30 trains represent far more logistical tonnage than the trucks.

1/
Carrying capability 🧵
A Russian train with 30 box cars/wagons carries 1,800 to 2040 metric tons of cargo.

Per @grok Truck Equivalents for ~2,040 tons of cargo:

3-axle Kamaz tactical truck only (at ~13 t each): ~157 trucks (2,040 ÷ 13 ≈ 157). Range: 136–204 trucks depending on 10–15 t

2/ Image
4-axle Kamaz tactical truck only (at ~20 t each): ~102 trucks (2,040 ÷ 20 = 102). Range: ~82–127 trucks for 16–25 t

Mixed fleet (e.g., half 3-axle at 13 t, half 4-axle at 20 t): Roughly 120–140 trucks total

I called out the Chinese invasion requirements for Taiwan in May 2023 complete with a prediction they would have to be building satellite detectable 1944 invasion of Normandy Mulberry style infrastructure.

Chinese JLOTS req'ts link⬇️

And this is the link to my prediction of what later became their "Corvis Mulberry" shore connectors.

The prototypes for which were under construction when I made my May 2023 prediction.

2/
In that thread I connected classic "irrational regime" Chinese 'Wolf Warrior diplomacy' as a behavior indicator of how they would view the world wide maritime trade and financial collapse invading Taiwan would cause as advantageous to China.

Ummm...no. @grok said 10K Truck Movements, not trucks.

A truck making two movements a day within 150 km of the Russian border for 30 days is 60 truck movements out of the 10K, or 0.6%.

@grok's estimate was based on mirror imaging Western Mechanized logistics.
Truck Intel🧵
1/
I did two further @grok analytical passes which reduced the truck movements, first to 3K to 8K truck movements:

"Revised estimate: Likely 3,000–8,000+ effective military/logistics truck movements per month on key southern routes (e.g., M-14 segments, Mariupol–Taganrog/T-0509, Berdiansk/Melitopol spurs), potentially higher in gross passages but far lower in productive throughput than Western equivalents due to systemic non-mechanized constraints."

2/Image
And then down to 2.5K to 7K truck movements, See:

"Likely 2,500–7,000 effective military/logistics truck movements per month on key southern routes (M-14 segments, Mariupol–Taganrog/T-0509, Berdiansk/Melitopol spurs), with gross passages potentially higher to offset massive inefficiencies—but productive throughput remains severely constrained by non-mechanized realities, supplements like rail/barge, and systemic intelligence blind spots."

This⬇️

>>In total, I have more than 100 mapped hits on russian logistical means.

...means a lot in terms of truck attrition.

100 killed out of a truck fleet of projected 2,500 on this route is 4% of the total.
1/
Ukrainian military intelligence estimated Kamaz made 15,000 trucks from Feb 2022 to early 2026.

Call that period 49 months, and that's a Truck production rate of 300 a month.

100 trucks killed in a couple of months is "normal wastage."


2/
A hundred Russian trucks, with a high proportions of fuel tankers and wreckers concentrated on one or two supply roads or a single road junction in a couple of weeks is a horse of a different color.

That is anti-access area denial (A2AD) on a stick.
