Muton

"They seemed to add some more armor plating for those Mutons."

Dr.Vahlen comment on Muton Elite

Muton Elites are the same type of the regular Mutons.Save that for their new Plasma Cannon and better armor than the original Mutons.Unlike the regular Mutons,they primarily don't really fight in frontline combat but they guard ships of the Aliens both down or still up in the air and usually guarding one Ethereal

Muton Elites are more efficient in combat than regular Mutons for their mental which is better than regulars,but still vulnernable to mind controls or Psi-based attacks.They are powerful fighters and in groups they are even more dangerous than ever.

IN 1962,they are very different in almost all ways.They don't guard for any Ships or Ethereals since Ethereals are not at the "Outsiders" command.They sport jetpacks and heavy ablative armor.They constantly throw Plasma Fields to hurt 1962 XCOM agents,making them very deadly.

Both in 1962 or 2015,they are still dangerous.
