Here is a paragraph from a case where the defendant forged a military document ...
Insurance Fraud Prosecutor Gooden Brown said the indictment alleges that Clark, formerly employed as a customer service representative by the Palisades Safety and Insurance Management Corporation located in Berkeley Heights, told her employer that she had been called to active military duty by the United States Army. An investigation by the Division of Criminal Justice - Office of Insurance Fraud Prosecutor determined that Clark submitted forged documents to support her claim, including a copy of U.S. Army active duty military orders in which she (Clark) was to report to Fort Dix, NJ en route to Fort Leonard Wood, MI, for a period of 12 months in support of "Operation Iraqi Freedom." While the investigation confirmed that Clark was a member of a New Jersey National Guard Reserve Component Unit, it was determined that Clark had not been called to active duty but had actually become employed at the American International Group (AIG) Insurance Company. During the eight-month period (March 24 through Nov. 28, 2003) in which it is alleged Clark perpetrated the fraud, the Palisades Corporation paid Clark her $12,678 salary.Definitely used the forgery for legal effect.http://www.state.nj.us/lps/newsreleases04/pr20040611a.html <-- Clickit
Still looking ...
I do recall a case where someone altered elements of the command history, not for anyone's benefit, and got six-six-and-a-kick for his trouble.
Also, when it's "memo for file," it's considered an official record--even if it's the CO's "private" documents (basically, any communication about personnel under his command is considered official).
