For example, the Italian and French words for various foods, some family relationships, and body parts are very similar to each other, yet most of those words are completely different in Spanish. Italian "avere" and "essere" as auxiliaries for forming compound tenses are used similarly to French "avoir" and "être". Spanish only retains "haber" and has done away with "ser" in forming compound tenses. However, when it comes to phonological structures, Italian and Spanish have undergone less change than French, with the result that some native speakers of Italian and Spanish may attain a degree of mutual comprehension that permits extensive communication.[citation needed]
What French word is similar to the Italian word "essere"?
être

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.
The rifle green beret is worn by whom?
Special Forces

Early writings on the subject tended to judge states by the realist criterion, as expressed by the historian A. J. P. Taylor when he noted that "The test of a great power is the test of strength for war." Later writers have expanded this test, attempting to define power in terms of overall military, economic, and political capacity. Kenneth Waltz, the founder of the neorealist theory of international relations, uses a set of five criteria to determine great power: population and territory; resource endowment; economic capability; political stability and competence; and military strength. These expanded criteria can be divided into three heads: power capabilities, spatial aspects, and status.
Besides military, what two other capacities were used to describe great powers in later times?
economic, and political
