[Aliens] Are the Colonial Marines a private military force?

I've wondered this for a while. Are the Colonial Marines a specialised unit that is part of a national military or are they a private military force wholly owned by Weyland-Yutani? Alternatively, are they a private military force that is simply hired by Weyland-Yutani as required?

The United States Colonial Marine Corps are a military force in service to the United Americas (although it could be argued that the government often serves the interests of Weyland-Yutani. You know how big corporations are)
