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 When the 77th Division infantry battalion was withdrawn.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.
9/ Image
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.

This is Grok analysis of one of my X threads is a good example of why farming out your thinking/analysis to AI is a really bad idea.

Grok accurately reflects a highly flawed US National Security consensus about small drones.😱

A Grok vs Drone Reality🧵

x.com/i/grok/share/B…
Grok focused on Ukrainian drone capabilities to the exclusion of actual fielded Chinese drone capability and literally eight decades old aviation technology like conformal fuel tanks which have also been applied to cruise missiles in the Chinese technological base for 20 years

The Chinese Sunflower-200 is it's clone of the Iranian Shahed-136. It appeared at Russia's Armiya-2023 show and in 2025 combat in Sudan.

The China Defense website says it has a 3.2-meter length, 2.5-meter wingspan, a flight speed of 160-220 km per hour with a maximum take-off weight of 175 kilograms, a combat payload of 40 kilograms and can fly up to 2000 kilometers.

I cannot begin to tell you how heartened I am by this development in Ukrainian combat barrier doctrine.

1/
Compare the picture above to my complaints about Ukrainian fighting doctrine in the Summer of 2024.

2/
Or my B*tching about its lack in the Summer of 2023 for the Russian Army

1560 dead Russian mortars and artillery tubes was 2/3 done by drones per ISW.

Drones are the primary counter-battery system on 21st century battlefields.

US Army field artillery branch OTOH is showing up to the counter-battery indirect firefight with knives, AKA the M109A6.

1/
The M109A6 Paladin 155mm/L39 caliber self-propelled gun is the T-62MV obr. 2022 of the artillery world.

The gun is inferior to every other major power's fielded SPG world wide.

The computerized fire direction system of the US Army Artillery is a overly centralized, decades old Star/mini-computer architecture, which has an electromagnetic signature so bright that it can be detected bouncing off the surface of the moon

Just...Reapers are not flying "Deep ISR" over Yemen.

They are dying due to a lack of electronic warfare equipment over Yemen.

I believe @noclador is overlooking the event @RyanO_ChosenCoy is calling out - The fall of Assad's Syria.

1/3 Image
Ukraine's HUR sent two drone teams with 150 drones to Syria in in June 2024 to support the Turkish supported Hayat Tahrir al-Sham.

2/3
By December 2024, Assad's regime fell because it could not counter Hayat Tahrir al-Sham (HTS) small drone airpower that Ukraine provided.

@RyanO_ChosenCoy is saying 25 such HUR teams with 80K drones would do in the Houthi from its lack of counter UAS capability.

See Grok⬇️

I see this F-35 procurement problems post is getting traction thanks to @elonmusk .

Let's add the F-35 problem list with bolts AKA fasteners.

1/
F-35 Fastener Corruption🧵 Image
I cannot begin to tell you all how fishy this passage from that article is:

"In addition to the F-35 production line at Ft. Worth, Texas, the commingling of the two types of bolts was also discovered at the Italian F-35

2/ Image
... Final Assembly and Check-Out (FACO) facility, but not the one in Japan, the DCMA reported."

Spot checking of aircraft production and depot level maintenance facilities fastener bins is a standard operating procedure for DCMA everywhere it has quality personnel.

Well designed Cope cages work against FPVs.

Why the West, and particularly the US Army, is in deep denial over that reality is rooted in the US Army's denial that the FPV anti-tank drone is replacing the ATGM for cost/performance reasons.

1/
The Ukrainian missile crews salvaging brand new $20K Stugna ATGM to make more FPV drones underlines the battlefield kinematic superiority of multi-copter drones to boost-glide ATGM.

2/
The ability of FPV's to operate in the dead ground makes them 2x as effective as ATGM at a lower cost:

1st Gen. FPV Drone =(π)5 km^2 78,539,816 sq m w-100% of coverage of targets

Tow Missile = (π)4.5 km^2 = 63,617,251.23 sq m at ~50% coverage 32.1 Sq km
