LE officers, whilst holding the same Queen's Commission, generally work in different roles from the DE officers.In the infantry, a number of Warrant Officer Class 1s (WO1) are commissioned as LE officers.In the second method, an individual may gain their commission after first enlisting and serving in the Junior Ranks, and typically reaching one of the senior non-commissioned officer (SNCO) ranks (which start at sergeant (Sgt), and above), as what are known as 'Direct Entry' or DE officers (and are typically and informally known as an 'ex-ranker').The third route is similar to the second, in that they convert from an enlisted to a commission; but these are only taken from the highest ranks of SNCOs, and are known as 'Late Entry' or LE officers.Commissioned officers are typically the only persons, in an armed forces environment, able to act as the commanding officer (according to the most technical definition of the word) of a military unit.A superior officer is an officer with a higher rank than another officer, who is a subordinate officer relative to the superior.

Others, including the Australian Defence Force, the British Armed Forces (BAF), Nepal Army, the Pakistani Armed Forces (PAF), the Swiss Armed Forces, the Singapore Armed Forces, the Israel Defense Forces (IDF), the Swedish Armed Forces, and the New Zealand Defence Force, are different in not requiring a university degree for commissioning—although a significant number of officers in these countries are graduates.
