OK, phaseshifter,
You really ought to contribute at least some of the higher-end thinking in this exchange.
A little logical strategic projection goes a long way.
According to Re sources: Antarctic Pop. is 1,000 non permanent incl. 200+ personnel rotating annually through the alleged South Polar Station. Supplied solely by air from NZ via McMurdo.
OK.
Given: the probability of unauthorized expeditions to FE Terra Australis by any Intrepid Explorer (ie Phaseshifter) looking for the IceWall and the logistical resources available to track and intercept said; A small highly mobile strike force is all that would reasonably be required and any/all IceWall Guard(s) on duty will be appropriately deployed to carry out their primary objective.
If you can't follow an easy pattern out for more than a few initial permutations; I doubt that you are versed enough to ken, much less grok, much of what I post.
Although you must be awarded points for dogged persistance, If you continue to shirk your intellectual due diligence in this matter; I may not bother to respond further.
