In the United States Army, United States Air Force, and United States Marine Corps, general is a four-star general officer rank, with the pay grade of O-10. General ranks above lieutenant general and below General of the Army or General of the Air Force; the Marine Corps does not have an established grade above general. General is equivalent to the rank of admiral in the other uniformed services. Since the grades of General of the Army and General of the Air Force are reserved for war-time use only, and since the Marine Corps has no five-star equivalent, the grade of general is currently considered to be the highest appointment an officer can achieve in these three services.
Gestures are a form of nonverbal communication in which visible bodily actions are used to communicate important messages, either in place of speech or together and in parallel with spoken words. Gestures include movement of the hands, face, or other parts of the body. Physical non-verbal communication such as purely expressive displays, proxemics, or displays of joint attention differ from gestures, which communicate specific messages. Gestures are culture-specific and can convey very different meanings in different social or cultural settings. Gesture is distinct from sign language. Although some gestures, such as the ubiquitous act of pointing, differ little from one place to another, most gestures do not have invariable or universal meanings but connote specific meanings in particular cultures. A single emblematic gesture can have very different significance in different cultural contexts, ranging from complimentary to highly offensive.
