A full-time National Guardsman toting two unloaded M-16 assault rifles sneaked onto the Michigan Stadium field before the Michigan-Michigan State football game.

WJBK-TV says security officials allowed the man into the stadium, where more than 113,000 people had gathered, because his weapons were empty and no ammunition was found.

Diane Brown, a spokeswoman for the university's department of public safety, said officials do not believe anything was done "incorrectly or improperly by police in any of the checkpoints.''

A member of the color guard reported the impostor, who was escorted out by police.

Brown said the unidentified man was compliant, and told officers he used his uniform as a ruse because he wanted to attend the Oct. 9 game but could not get a ticket.
