The word "noncom" is a noun that is short for "non-commissioned officer." It refers to a military officer who has been promoted from the ranks of enlisted personnel (regular soldiers) but does not hold a commission like a commissioned officer (such as a captain or a lieutenant). Noncoms typically have more experience and responsibility than regular soldiers and often lead and supervise them.
In a more formal context, you might refer to noncoms as "non-commissioned officers," but in casual conversation, "noncom" is perfectly acceptable. Noncoms can include ranks such as sergeants and corporals.
While "noncom" itself doesn’t have idioms or phrasal verbs associated with it, in military contexts, you might hear phrases like: - "Fall in line": This means to follow orders or conform to the group's standards, often used in relation to following a noncom's leadership.
