The Nepalese ex-solider will protect both Rooney's home and that of his team-mate and neighbour Wes Brown, who lives in a £4m pad next door in Prestbury, Cheshire.
Both players are likely to be included in England's World Cup squad, and a recent spate of violent burglaries at the homes of Premier League players - including United midfielder Darren Fletcher - has prompted 24-year-old Rooney and 30-year-old Brown to step up security.
"The Gurkhas have a formidable reputation," an Old Trafford insider told The Sun.
"We've been told this guy was military decorated. You wouldn't want to cross him."
According to the report, the Gurkha will have his own quarters at Brown's house.
