Medal of Honor Marine sues ex-employer for defamation

President Obama delivered the nation's highest military honor to Dakota Meyer. NBC's Brian Williams reports.

A Marine sergeant who received the Medal of Honor from President Barack Obama last September for saving 36 comrades has sued  his previous employer, a major weapons manufacturer, for defamation, the Wall Street Journal reported Tuesday.

Details weren't released at the time of the original lawsuit in June, the Journal added, but Dakota Meyer filed an amended complaint on Monday in which he accuses BAE Systems of retaliation after he criticized the company for selling sniper scopes to Pakistan that he said were better than what U.S. soldiers got.

"We are taking the best gear, the best technology on the market to date and giving it to guys known to stab us in the back," Meyer wrote to his superviser, according to the lawsuit. "These are the same people killing our guys."

 Meyer says he later tried to return to a job with an earlier employer but was spurned when his BAE supervisor made false claims about a drinking problem and that he was "mentally unstable."

BAE, for its part, stated: "Although we strongly disagree with his claims, which we will address through the appropriate legal process, we wish him success and good fortune in his endeavors."

A colleague at his earlier employer, Ausgar Technologies, told ABC News that Meyer was "an outstanding employee."

"He exhibited a maturity for his age and an insightful capability to get the job done and provide recommendations to improve on what we are doing," said Tom Grant, a retired naval officer and a senior program manager at Ausgar. "I was very impressed while he was working for us."
