Given that the regular Naval fleet units of any nationality tend to be highly mobile and could be called away at short notice, most colonies finance locally trained and equipped armed merchants whose primary function is to discourage piracy, but also to make it harder for other nationalities to mount small raids.

Star Guard ships are usually crewed with auxiliary crew - either part-timers or reservists usually with a small cadre of full-time regulars to take command and senior positions.

It is, unfortunately, the case that Star Guard units do not generally attract the cream of the officer corps.

Star Guard normally only operate within their home system for legal or constitutional reasons, but their ships are interstellar, and can operate in neighbouring systems for pre-determined periods on specific operations, (for example in anti-pirate sweeps etc).

Typically they will spend no more than 50 days away from their home station.
