Watch the extra ALIENS disk that comes with the quadrilogy set. Ron Cobb designed the emblem, the design was along the lines of the squadron patches and nose art applied to WWII and modern aircraft, etc. Art that added a touch of humor and bravado to a serious mission, but with a definite serious meaning behind it all. The Marines from ALIENS were a part of a special unit that dealt with hostile aliens. Deal with it.
Butters you are about 98 percent correct in that statement.
Never is it mentioned that they are a special aliens unit or what ever.
The weyland yutani chock says " and found something never recorded once in over 300 surveyed worlds.
A creature that gestates inside a living human host, these are your words, and has concentrated acid for blood"
Now what she is saying is that they have never encounter anything like the alien. Never does she say that we have never encounted alien life.
When Hudson says this isn't another bug hunt obviously indicates that there squad has encountered some form of extraterrestrial life.
Just because frost doesn't know what a xenomorph is doesn't mean they have not encounted ET's or some other life form.
Xenomorph is the term used to define the alien from the franchise.
The arcturian reference is obviously some sort of life form.alien or biologically engineered by humans is unknown because there is no other mention of them apart from that scene.
The bug stomper emblem was put in as a joke and because Cobb likes ww2 nose art. I don't think it was mention to imply that they've encountered the alien / xenomorph before.
But I do believe they have encountered other forms of life or have at very least gone looking for it.
The "bugs" that Hudson is referring to aren't the xenomorph/alien species.
Now the only person who can say for sure and set the whole story straight is James Cameron and I don't think he's on this forum
