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. 3/
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. 4/
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. 5/
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 When the 77th Division infantry battalion was withdrawn.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 6/
...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. 7/
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. 9/
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.
Ukraine has achieved "Drone air superiority" over those roads rivaling WW2's Summer 1944 Allied air superiority over German occupied Normandy.
As a result, the Russian truck fleet is taking unsustainable attrition, particularly of its fuel tanker fleet. 2/
This AFU fuel interdiction campaign is causing panic:
"Fuel shortages are beginning in Sevastopol. This is the beginning of the consequences of the enemy's systematic strikes on oil refineries and tanker trucks along the land corridor to Crimea." 3/
Texas has seven unique advantages in terms of infrastructure, political culture, and resource geography that make it uniquely suited to be the next industrial heartland of the USA.
The seven industrial development advantages of Texas 🧵 1/
1. About 94% of land in Texas is privately held. This vastly limits what the Federal, State and local governments can do to in terms of regulations and NIMBY games.
2/
2. Texas is mostly flat. Texas hill country is small beer compared to the Appalachian and Sierra Nevada mountain ranges. This compounds with #1 for industrial development.
3. Texas has a lot of water compared to the US west & sea access.
This is one of the most logistically incompetent hot takes by any German journalist in the Russo-Ukrainian War.
95% getting through is a 5% loss rate per trip
95%(x) for 10 to 20 kills means x = 200 to 400 trucks on this route
10 trips means 40% total fleet loss - 80 to 160 trucks
1/
You can follow the 5% loss curve in this 500 unit fleet at 10 exposures in the graphic below.
A 40% fleet loss in 10 days from a 5% drone loss rate is logistical collapse for the Russian Army in occupied Ukraine.
Only some trying to get AfD eyeballs would say different.
2/
This leaves out the fact that the Russian Army doesn't use *ANY* mechanized logistical enabler like pallets, Truck D-rings, forklifts, or telehandlers.
Russian trucks are in the drone kill zones 3 times as long as a Western truck due to loading times.
"The DF-26 intermediate-range ballistic missile, with a range of approximately 4,000 to 5,000 kilometers, was specifically designed and publicly nicknamed by Chinese military analysts as the "Guam Killer.""
As laid out by warquants -dot- com, China is buying one million OWA drones to destroy all US/Taiwan/Taiwan allied military logistics from Guam to the China coast.
A quantity of one million "Shaheed plus" class OWA drones has quality all its own.
