The U.S. Army black beret (having been permanently replaced with the patrol cap) is no longer worn with the new ACU for garrison duty. After years of complaints that it wasn't suited well for most work conditions, Army Chief of Staff General Martin Dempsey eliminated it for wear with the ACU in June 2011. Soldiers still wear berets who are currently in a unit in jump status, whether the wearer is parachute-qualified, or not (maroon beret), Members of the 75th Ranger Regiment and the Airborne and Ranger Training Brigade (tan beret), and Special Forces (rifle green beret) and may wear it with the Army Service Uniform for non-ceremonial functions. Unit commanders may still direct the wear of patrol caps in these units in training environments or motor pools.

Who was the Army Chief of Staff at this time?
Answer: General Martin Dempsey

Cultural practices in the Americas seem to have been shared mostly within geographical zones where unrelated peoples adopted similar technologies and social organizations. An example of such a cultural area is Mesoamerica, where millennia of coexistence and shared development among the peoples of the region produced a fairly homogeneous culture with complex agricultural and social patterns. Another well-known example is the North American plains where until the 19th century several peoples shared the traits of nomadic hunter-gatherers based primarily on buffalo hunting.

What did geographical zones encourage the sharing of?
Answer: Cultural practices

CD-Vs are not to be confused with Video CDs (which are all-digital and can only be played on VCD players, DVD players, CD-i players, computers, and later-model LaserDisc players, such as the DVL series from Pioneer that can also play DVDs). CD-Vs can only be played back on LaserDisc players with CD-V capability. VSDs were the same as CD-Vs, but without the audio CD tracks. CD-Vs were somewhat popular for a brief time worldwide, but soon faded from view. VSDs were popular only in Japan and other parts of Asia, and were never fully introduced to the rest of the world.

In what areas of the world were VSDs popular?
Answer:
only in Japan and other parts of Asia
