The Army Brief: Deadly attack at Pentagon; Afghans arrive in U.S.; Teleworking tips; and more...

Welcome to The Army Brief, a weekly look at the news and ideas shaping the service's future. 

Pentagon officer mourned. George Gonzalez, a Pentagon Police Officer and Army veteran, was killed Tuesday on the Pentagon bus platform by a 27-year-old man from Georgia, the FBI tweeted. Gonzalez's family said in a statement that he "loved his country, his family, and the Yankees."

First Afghans reach U.S. The first group of Afghan interpreters seeking to relocate to the United States arrived at Fort Lee in Virginia, Defense One reports. More than 2,000 interpreters and their families who have nearly completed their paperwork are still waiting for their flight to the U.S.

Wifi safety. With people leaving their homes to work and travel after more than a year of teleworking, the NSA is warning national security employees to protect their computer data by avoiding public wifi, Defense One reports. If public wifi can't be avoided, they recommend using a corporate-provided virtual private network, or VPN.

On this day in 2011, an Army Chinook helicopter was hit by an RPG in Afghanistan, killing 30 Americans, many of them Navy SEALs. The attack was the deadliest helicopter crash in U.S. Special Operations history.
