EO meaning in Military and Defence ?

Equal opportunity is a state of fairness in which individuals are treated similarly, unhampered by artificial barriers or prejudices or preferences, except when particular distinctions can be explicitly justified. The intent is that the important jobs in an organization should go to the people who are most qualified – persons most likely to perform ably in a given task – and not go to persons for reasons deemed arbitrary or irrelevant, such as circumstances of birth, upbringing, having well-connected relatives or friends, religion, sex, ethnicity, race, caste, or involuntary personal attributes such as disability, age, gender identity, or sexual orientation.

According to proponents of the term, chances for advancement should be open to everybody interested, such that they have "an equal chance to compete within the framework of goals and the structure of rules established". The idea is to remove arbitrariness from the selection process and base it on some "pre-agreed basis of fairness, with the assessment process being related to the type of position" and emphasizing procedural and legal means. Individuals should succeed or fail based on their own efforts and not extraneous circumstances such as having well-connected parents. It is opposed to nepotism and plays a role in whether a social structure is seen as legitimate. The concept is applicable in areas of public life in which benefits are earned and received such as employment and education, although it can apply to many other areas as well. Equal opportunity is central to the concept of meritocracy.
