US Military of Inkwell Isle

"After seeing NATO soldiers wearing military uniforms that aren't modern but are from the 18th century and the 19th century being stationed in Castlehaven, which reminds me of the French and Indian Wars, American Revolutionary War, the Napoleonic War, the American Civil War, and more, what I see is the US Armed Forces wearing WW2-era uniforms and possessing WW2-era stuff out there. Now that reminds me of when I was wearing a Joseon era soldier outfit that soldiers from that dynasty wore like the rest of these ROK guys in Castlehaven before we would capture Stella and bring Trinket back. Didn't remember that. Now I'm wearing something that's... Imperial Japanese Army-like? Well, I hope nobody would try to kill me nor I don't want to hurt anybody else because I don't want to commit any war crimes again, okay?"

The US Military of Inkwell Isle is the military part of United States Armed Forces that they are protecting at Inkwell Isle.

Only happened during The Devil's Deal that they are based on 1930s US Army because Inkwell Isle is different styled (which is similar to his experience to the British Military of Castlehaven (based on Redcoats from the American Revolutionary War), the French Military of Enchancia (based on pre-French Revolution/white-coated French Royal Army soldiers), the Italian Military of Tamriel (based on Ancient Roman legionnaires), the Philippine Military of Encantadia (based on pre-colonial Philippine warriors), Chinese Military of Peace Valley (based on ancient Chinese/imperial Chinese soldiers), Egyptian Military of Agrabah (based on ancient Egyptian warriors), Mexican Military of Coatl (based on Mesoamerican/pre-Columbian warriors) British Military of Middle-Earth (based on medieval knights and warriors), US Military of Oz (based on World War I-era United States Army), Norwegian Military of Asgard (based on vikings), and more, just before, between and after to that, which are all before each major events could happen).

Until after Cuphead and Mugman save all everyone from The Devil's Deal (like WW3),they will be based on WW2 US Army that they will protect Inkwell Isle.
