Black Egret Armored Gunner

"After the Last Day was over, these new type of heavy troopers are called the 'Black Egret Armored Gunner.' After all, the Black Egrets must've survived all of these ruckuses that the nukes have made for. We can therefore kick some Enclave butt by giving them some training. I knew fallout's just killin' me."

--Su Ji-Hoon, Deserted by Hopelessness

The Black Egret Armored Gunner is the post-Last Day heavy trooper serving for the Black Egrets that they are post-apocalyptic heavy trooper under the command of Parasoul and her younger sister.

They would be appeared in post-Last Day when Parasoul and Canopy Kingdom trained them for prepare to survive and defend, which they would wear the Black Egret version of T-51 power armor and Fallout heavy weapons since Black Egrets trained their Juggernauts in USRAC War

Therefore,the post-Last Day making Black Egrets would against the Enclave and Enclave troopers due to survivals,defend and support others.
