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 When the 77th Division infantry battalion was withdrawn.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.

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.

Stephen Blank has always had a clear US policy view of Russia:

"Moreover, Putin and his circle consistently advance two intertwined claims:

1. Ukraine is inherently Russian;

2. this war steps from NATO’s alleged attempt to turn

1/
euromaidanpress.com/2025/01/22/tru…
...its supposed vassal state Ukraine into a member against Russia’s will.

Though some self-proclaimed experts still peddle this nonsense, this war’s true purpose is unmistakable:

2/
...the restoration of the Russian empire, without which Putin’s power – and that of his likely successors – cannot persist."

I'll add the following:

The arrival & mass production of Chairman Xi's Corvus Mulberry barges (pictured below behind a Chinese car ferry⬇️)...

400 Houthi aerial drones, cruise missiles and ballistic missiles were fired at/near USN ships since Oct 2023

120 SM-2 & 80 SM-6 missiles, 160 five-inch main guns rounds, plus a combined 20 Evolved Sea Sparrow and SM-3 missiles engaged them.

Drone War Cost Trades 🧵
1/ Image
Tyler Rogoway has reported the following missile costs:

SM-2 Block IIIC - $2,530,000 per missile.
SM-6 - $4,270,000 per missile.
Evolved Sea Sparrow Missile (ESSM) RIM-162 Block II - $1,490,000 per missile.
SM-3 -$12,510,000 for the Block IB, and $28,700,000 for the Block IIA
2/ Image
So:

120 SM-2 * $2.53 million = $303.6 million
80 SM-6 * $4.27 million = $341.6 million
12 ESSM (guess) = $17.88 million
6 SM-3 IB (guess) * $12.51 million = $75 million
2 SM-3 IIA (guess) * $28.7 million = $57.4 million

The fire and forget millimeter wave (MMW) radar guidance AGM-114L "Hellfire Longbow" being referred in the War Zone post as "a new anti-drone armament" for the LCS actually ceased production in 2005 and reaches end of life in 2025.

1/
One of the reasons the AGM-114L was dropped from the US Army M-Shorad is the US Army didn't want to pay money to recertify the AGM-114L inventory...

2/
...with the AGM-179 Joint Air-to-Ground Missile (JAGM) equipped with dual-mode Semi-Active Laser (SAL) and millimeter wave (MMW) radar seeker just entering production.

It is a bad week to be Russia.

Qatar, one of the biggest LNG exporter, just announced it's new six MTPA (million tonnes per annum) nitrogen fertilizer plant.

The chemical process involved is natural gas->ammonia -> urea for a

...vertically integrated facility.

This new Qatar facility means Middle Eastern fertilizer industrial plants have now displaced Russia on the world fertilizer market.

2/
This makes Russia falling out of the world Ag-sector fertilizer supply chain a non-event going forward.

The Qatari sheiks made a good move here to capture value up the supply chain from energy.

Plus, Urea and Ammonia store far better than liquified natural gas.

I disagree with the thoughts in this post for multiple reasons.⬇️

1st, Ukraine made a systematic effort in Oct 2024 to take out multiple Russian alcohol distilleries.

So distilleries are on the AFU strategic bombing list.

1/
2nd, there are a lot of things that alcohol is a chemical feedstock for that Russia desperately needs to make.

I've talked about synthetic rubber for tires in another thread.


2/
A short list of Russian industrial alcohol uses include:

o It's used as an industrial solvent.
o It's used as a precursor for numerous plastics.
o It's used as a precursor for some explosives.

Ukraine struck another Russian alcohol plant?

I'm beginning to think the Russians have been using alcohol to make butadiene based synthetic rubber.

My WW2 US mobilization resources say grain produced alcohol was the primary chemical feedstock for the synthetic rubber

1/
...in US tires until August 1944.

The process was invented by a Russian, Via wikipedia:

"The Russian chemist Sergei Vasilyevich Lebedev was the first to polymerize butadiene in 1910....

2/
...In 1926 he invented a process for manufacturing butadiene from ethanol, and in 1928, developed a method for producing polybutadiene using sodium as a catalyst.

The government of the Soviet Union strove to use polybutadiene as an alternative to natural rubber ...
