AT&T on Monday announced that the company secured a U.S. Army contract for cloud-based communications systems.

The deal, AT&T officials said, would unify and modernize communications for nearly 1 million users around the world, including voice, video, chat, instant messaging, and screen sharing capabilities accessible on desktop computers, laptops, and approved mobile devices.

Because the system is cloud-based, AT&T added that it will manage the services and that the Army will not need to buy new equipment.

The company suggested that its systems could allow commanders to collaborate with their staffs or direct troop movements using live video from anywhere in the world — or enable mechanics to share screens from different locations to conduct faster repairs.

The services will be delivered in both “classified and highly secure unclassified formats.” Terms of the contract were not disclosed.

“We’re honored to deliver capabilities that complement our vision of a ‘network of the future’ for the Army,” Kay Kapoor, president of AT&T Global Public Sector, said in a statement.
