The Ravagers have some sort of fantastic technology that allows them to store a large number of large bodies in a very confined space. Why not simply inundate the world in a torrent of troops.
The ravagers have the ability to bomb cities form above and have clearly advanced energy weapons. Why don't they just waste anything we have that can reach them in orbit and just bomb the earths population with the energy weapons that break up human beings on the molecular level?
Why not deploy hectors Mk1s' and M K2s'in larger groups?
Why did they wait so long to cyberize their bug soldiers?
How come the EDF didn't try nuking the enemy in certain locations?
No artillery of any sort is used by EDF. No cruise missiles either.
