I haven't tried this, but it may create the effect you want.
Make the marine have 0 sight visibility.
Create a region of the given sight requirements (using negative regions to cancel out areas you don't want, if you don't want it a square/circle), and attach it to the marine with an offset. Then, create a revealer inside the region created.
Potential folleys: I don't know if attached regions done with an offset update according to current angle of unit.
Another potential solution:
Attach an invul/untargetable invisible unit with the sight wanted onto the marine, using an absurd attachment point (away from his model).
Ok got this to work rather well with the region, Now is there a way to make the region stay connected to the marine if he moves? so he always can see ahead?
How would I make it so a unit can not see behind him, allowed a melee to sneak up on a marine, per say.

@DirtyDevious: Go
Attach region to unit is probably a good place to start.

Haha good idea, i was looking in regions preferences like points
