Information may include video and digital data. GBS has become a critical piece of the DoD's intelligence, surveillance and reconnaissance architecture. An advancement in satellite communications , GBS fills two key military communications requirements: Beginning in 1998, GBS began broadcasting via communication payloads on two Ultra High Frequency Follow-On (UFO) Ka-band augmented satellites and more recently all Wideband Global SATCOM (WGS) satellites (via Ka-band only).

686-564: A fair and just social contract . The purpose of classification is to protect information. Higher classifications protect information that might endanger national security . Classification formalises what constitutes a "state secret" and accords different levels of protection based on the expected damage the information might cause in the wrong hands.

By November 1989 Pentagon briefers were laying out plans to reduce army end strength by 23%, from 750,000 to 580,000. A number of incentives such as early retirement were used. In 1990, Iraq invaded its smaller neighbor, Kuwait , and U.S. land forces quickly deployed to assure

Documents and other information must be properly marked "by the author" with one of several (hierarchical) levels of sensitivity—e.g. restricted, confidential, secret, and top secret.

This process often includes security clearances for personnel handling
1862-738: A strategy of seizing the coastline, blockading the ports, and taking control of the river systems. By 1863, the Confederacy was being strangled.
