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 When the 77th Division infantry battalion was withdrawn.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.
10/
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.
Injection molding gets you a lot of one thing cheaply. Think lots of fiber optic guided FPV drones, which are immune to radio jamming.
3D/AM allows a lot of modifications to meet the changing requirements of war. Think rapidly evolving Ukrainian interceptor drone designs.
2/
The issue for Ukraine versus Russia is Ukraine has to more widely disperse its industrial base because Russia has a bigger cruise and 500 km(+) ballistic missile production base.
Ukraine's need to disperse production and evolve drones means 3D/AM is a better industrial fit.
3/3
The Coyote I was a propeller interceptor like the Ukrainian FPV's, but it wasn't "enough" for the higher end drone threat like the TB-2 Bayraktar.
2/
So the US military abandoned kinetic solutions the lower end drone threat.
And it has to pretend that high power microwave weapons and jamming will be the answer to fiber optic guided FPV's at weed height and grenade dropping drones behind tree lines.
The arrival of the Ukrainian Gogol-M, a 20-foot span fixed-wing aerial drone mothership, with over a 200km radius of action while carrying a payload of two 30km ranged attack drones under its wings, underlines the impact of low level airspace as a drone "avenue of approach."
2/
The Gogol-M flys low and slow, below ground based radar coverage like a helicopter.
It opens up headquarters, ground & air logistics in the operational depths to artificial intelligence aided FPV drone attacks.
This is the main example of one of the most unprofessional delusions held by the US Navalist wing of the F-35 Big/Expensive/Few platform and missile cult.
Russian fiber optic FPV's have a range of 50km - over the horizon!
Drones simply don't have ground line of sight issues like soldiers do.
Drones can see in more of the electromagnetic spectrum than humans.
And the US Army refuses to buy enough small drones (1 m +) to train their troops to survive on the drone dominated battlefield.🤢🤮
2/3
"Just send a drone" is the proper tactic for almost everything a 21st century infantryman does from patrolling, raiding enemy positions, sniping and setting up forward observation posts.
3/3
The odds are heavily in favor of the IDF having parked Hermes drones with "Gorgon Stare" technology over Tehran to hunt Iranian senior government officials.
