I think that the Aussie squad is basically made to be something you only build one of (because it's not exactly stellar in combat). I like using them as a second engineer going around and building the one sided cover everywhere for my infantry sections to use.
Tbh, as cool as I find the aussie squad to be, the rest of the BG feels kinda meh. Oh boy, I can boobytrap a point to fire one artillery shell. Oh boy, australian for the motherland but mid.
The 2 pounder AT gun is actually really good imo considering how much bigger the light vehicle phase is even in 4v4.
that's what I thought. Nothing really useful overall. In the meantime, Axis gets invisible troops. That tracks.
