The US Army is the latest recruit in Apple’s creeping invasion of territories that used to be exclusive to other platforms.

The American military is integrating Macintoshes into their computer systems to make their setup harder to hack, according to a report from Forbes.com. Lt. Col. C.J. Wallington, a division chief in the Army’s office of enterprise information systems, says that since Macs haven’t been a common target of attacks, fewer hacks have been designed for them and adding Macs to the mix will make the Army’s systems less prone to destabilization with a single attack.

Apple hardware has already been working out well for the military. Wallington says that X Serve servers from Apple, which have become commonplace equipment in the Army’s systems, have proven themselves in use. Of the X Serves, Wallington says

Those are some of the most attacked computers there are. But the attacks used against them are designed for Windows-based machines, so they shrug them off.”
