I've done some basic mock ups of how the backpack works and it turns out that that the SRM5 launcher with 10 spare SRM's works perfectly, and fits perfectly into the sort sizes the Golem elemental is supposed to be. Its even got room to rotate and manuver the rockets from the backpack into the launcher.
Quite why the illustration has the actual rocket launching tubes look as they do i have no idea. Perhaps the door of the launching tube a 2 part hatch that is forced open when the missile leaved the launcher, i dont know.
Really coming together Animal. Some one in Clan Ghost Bear should give you a bloodname.
Thanks, my name would be "Animal", i can't think where i get my inspiration from sometimes.
