When the Antarctic retaliations happen, all 16 ICBMs launch from the Gorgaroth class sub. The ICBMs launch from the submarine right as antarctic troops land on gorgarothian coasts, killing most of them. Gorgarothian forces manage to push back the troops from all directions. Many troops set up forts before the next attack. Gorgarothian troops easily push back the enemies after the ICBMs eliminate almost all of the antarctic troops. And yes, Gorgaroth knows that they are shoot missles at basically there own territory.
