Considering we would be unlikely to ever outside of a major war (ie: China) conduct such a large scale amphibious assult that it would require an entire ARG would it not be better to give each of our combat brigades an amphibious element similar to what the 3rd brigade is acquiring with the 2nd Battalion?
Only spit balling here but I figure if we lack enough personnel for 3 combat brigades and a full ARG, can't deploy both an ARG and a combat brigade that it would be better to give some amphibious capability to each combat brigade allowing them to secure a beach head to bring ashore the rest of the combat brigade.
Just my 2 cents.
normally (normally)
specials secure transport infrastructure, ports, airport, hold and wait for big army to arrive
that was plan A at one stage when there was concern about which way fiji might have turned out,
so the phatship combat vignette for fiji was, specials land, secure criticals, get ARH support in doing the job, ADG's progressively land and secure transport infrastructure, big army arrives, recover nationals, foreign nationals and anyone else other countries seek assistance on
pity about the ARH's being a woftam
