Marines are produced by Military Garrisons designated for training. Each Small Military Garrison decreases planetary Crew Unit production by 10 and produces 10 Marine Units, who may be used as Marines or Boarding Parties (in game terms, they are functionally identical).
Being intelligent creatures, they will find their own way to your permanent bases and Major Planets, and so can be used as soon as they are produced. Your empire will have a Personnel Treasury from which you may draw Crew Units and Marines.
