An Atlas V rocket lifts off from Cape Canaveral Air Force Station at 5:15 p.m. on 24 February 2012 carrying the first satellite of the Mobile User Objective Systems (MUOS) for the US Navy who, it turns out, is in charge of providing all narrowband communications for all US military forces and many allies. The images show liftoff through solid rocket booster separation.

A description of MUOS from a United States Navy Space and Naval Warfare Systems Command press release:

The Mobile User Objective Systems is the Defense Department’s next-generation narrowband military communications system. It will support a worldwide, multiservice population of UHF band users, providing increased communications capabilities to smaller terminals while still supporting interoperability with legacy terminals. MUOS is designed to support users that require mobility, high data rates and improved operational availability. The system will provide greater than 10 times the system capacity of the current UHF constellation.
