Fortefighter is nothing like any class in PSO v.v please don't put it as such.

Figunners is closest to a HUcast/HUcaseal
Wartecher is closest to a HUnewearl/HUmar
Guntecher is closest to a RAmar/RAmarl
ForteGunner is closest to RAcast/RAcaseal
ForteForce is all of the PSO Forces

you can get more in depth than that, but really not necessary...for example
a Cast or Beast ForteTecher are more like FOmarls and FOmars
