While gas pain is common and can afflict a child at any age, it is particularly bothersome in newborns and young infants between one and four months of age, as their immature guts are developing. Furthermore, some babies seem to suffer more than others due to inborn and environmental factors.
The United States Public Health Service Commissioned Corps (PHSCC),[5] also referred to as the Commissioned Corps of the United States Public Health Service,[6] is the federal uniformed service of the U.S. Public Health Service (PHS), and is one of the seven uniformed services of the United States.
For example, an enlisted soldier with MOSC 11B works as an infantryman (his MOS), and is part of CMF 11 (the CMF for infantry). Commissioned officers are classified by their area of concentration, or AOC. Just like enlisted MOSCs, AOCs are two digits plus a letter. Related AOCs are grouped together by specific branch of the Army or by broader in scope functional areas (FA). Typically, an officer will start in an AOC of a specific branch and move up to an FA AOC. Warrant officers are classified by warrant officer military occupational specialty, or WOMOS.
