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 When the 77th Division infantry battalion was withdrawn.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.
The following is evaluation is based on a number of professional discussions:
This CRPA found in a shot down jet Shaheed is reported to be Russian built. This is highly doubtful as the design and construction style looks far too professional for Russian industry.
Bluntly - Russians tend towards cheapskate up-front capital manufacturing solutions.
The upshot is injection molded and die cast components are not a common feature in Russian designs as tooling for manufacturing designs is expensive up front,
2/
...even if the mass production unit costs are lower.
In addition, Western style SMA RF connectors are not a feature of the Soviet technology base.
" Please summarize the pre-World War 1 to 1942 career of merchant armed raiders and compare that data to Ukraine's recent drone attack in the Mediterranean with a drone armed commercial vessel."

This is @grok's final summary:
"In essence, Ukraine's approach modernizes the raider concept—swapping guns for drones and merchant disguises for stealthy launches— but lacks the historical volume due to the conflict's constraints.
3/
In Donetsk, reconnaissance operators face constant drone surveillance, electromagnetic degradation, and hyper-local combat conditions that invalidate long-held assumptions about stealth and standoff intelligence, surveillance, and reconnaissance (ISR).

This article contends that NATO must, with urgency, reform its reconnaissance doctrine, training, and force structure to survive and efficiently operate in a drone-saturated battlefield."
Every competent USN surface officer knows in their gut an anti-aircraft cruiser should not be operating with downed identification friend or foe (IFF) and Link-16 data link with no E-2 Hawkeye AEW support.
That sound drama isn't World War One or any "medium intensity" conflict since 1918.
It is the sound of how 21st century Peer-to-Peer conflict is fought.
A conflict Western ground militaries are obsolescent in equipment to face.

That Russo-Ukraine War video is a soundscape US Army National Training Centers are too obsolete/incapable of replicating, because US Army flag ranks are allergic to training with high densities of small/cheap/many FPV drones.
SHORAN was a WW2 blind bombing system using two radio stations and an electromechanical computer.
In 1938 an RCA engineer named Stuart William Seeley, while attempting to remove "ghost" signals from an experimental television system, discovered he could measure distances 2/
...by time differences in radio reception.
Instead of building a radar unit with this discovery, he proposed using this technique for precision ground-based radio beacon navigation bombing aid.
