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 When the 77th Division infantry battalion was withdrawn.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/

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.
One of the most difficult issues in researching & writing about electronic warfare in WW2’s Pacific Theater is it’s systematic exclusion from the USN’s official histories. This exclusion was as systematic was it was intentional.

The war diaries of the US Navy are both digitized and available on the Fold3.com service.
A simple search on the radar decoy code name “Window” in the WW2 War Diaries gets thousands of hits. 2/ fold3.com
Window was one of the names for radar dipole decoys dropped from A/C, rockets, bombs and artillery.
The Japanese were both technically skilled and increasingly proficient in its use by 1945.
And, like those thousands of Fold3.com war diary hits, their efforts 3/

Nor are squadies the only payload these multicopter "lift rings" can move around.
The Ukrainian “Thunder” loitering drone recce-ammunition uses the lift ring staging concept to lift it's munition and then acts as a radio relay naturasigorta.com/ukrainian-loit…
Conceptually, staged drones are a partially disposable form of air to air refueling.
This reusable multi-copter staged munition drone concept certainly makes a USS Unicorn style VTOL aircraft & drone carrier a while lot more interesting.
