S.H.I.E.L.D.: Deals with Terrestrial threats to the world.
S.W.O.R.D.: Deals with Extra-Terrestrial threats to the world.
A.R.M.O.R.: Deals with Extra-Dimensional threats to the world.

This is an Extra-Terrestrial force creating Terrestrial threats to the world. It could be either, but i've changed it to S.W.O.R.D. to better fit the established stuff.
