It is an individual or a company that provides goods of services to another organisation on the basis of a contract.
in this context, it likely means someone who works for a private military company, often contracted by the US government to provide private security services. There are also terms security contractors or private military contractors.
They are often individual who are ex military, SF or close protection police.
