Seems that I remember this scenario from SouthEast Asia, Vietnam.
"A former U.S. Marine fighting in Ukraine was killed in combat this week, his family said, according to a report on Thursday.
Willy Joseph Cancel, 22, had been working for a private military contracting company in Ukraine since March 12 or 13. He was killed in fighting on Monday, and his body has not been recovered, according to the report."
Willy Joe Cancel had a full time job as a Tennessee corrections officer. The CIA, read USA, involvement in VietNam began in the 1950's.
I hope that the private contracting firm that hired him to fight in Ukraine is identified. I could not find the name of the company in any press release to this time.
Next question is Ukraine contracting with these suppliers of US former military personnel, using the funds provided by the USA?
