The interviews and research reveal a series of deceptions, mistakes and squabbles that have hindered the volunteer drive that began after Russia’s full-scale invasion in February 2022, when President Volodymyr Zelensky of Ukraine called for help. “Every friend of Ukraine who wants to join Ukraine in defending the country, please come over,” he said. “We will give you weapons.”
Thousands answered the call. Some joined military groups like the International Legion, which Ukraine formed for foreign fighters. Others took roles in support or fund-raising. With Kyiv, Ukraine’s capital, under attack, there was little time for vetting arrivals. So people with problematic pasts, including checkered or fabricated military records, became entrenched in the Legion and a constellation of other volunteer groups.
Asked about these problems, the Ukrainian military did not address specific issues but did say it was on guard because Russian agents regularly tried to infiltrate volunteer groups. “We investigated such cases and handed them over to law enforcement agencies,” said Andriy Cherniak, a representative for Ukrainian military intelligence.
‘A Million Lies’
One of the best-known Americans on the battlefield is James Vasquez. Days after the invasion, Mr. Vasquez, a Connecticut home-improvement contractor, announced he was leaving for Ukraine. His local newspaper told the tale of a former U.S. Army staff sergeant who left behind his job and family and picked up a rifle and a rucksack on the front line.
Since then, he has posted battlefield videos online, at least once broadcasting his unit’s precise location to everyone, including the enemy. He used his story to solicit donations. “I was in Kuwait during Desert Storm, and I was in Iraq after 9/11,” Mr. Vasquez said in a fund-raising video. He added, “This is a whole different animal.”
Mr. Vasquez, in fact, was never deployed to Kuwait, Iraq or anywhere else, a Pentagon spokeswoman said. He specialized in fuel and electrical repairs. And he left the Army Reserve not as a sergeant as he claimed, but as a private first class, one of the Army’s lowest ranks.
Still, Mr. Vasquez had easy access to weapons, including American rifles. Where did they come from? “I’m not exactly sure,” Mr. Vasquez said in a text message. The rifles, he added, were “brand-new, out of the box and we have plenty.” He also tweeted that he should not have to worry about international rules of war while in Ukraine.
