If you buy an FOO as the first thing, then as B0 its the easiest thing to find it on the HQ lists as it is right in your face under A0. So I always buy my observer as item No. 1. So no paging through lists of stuff to find that observer that you tacked onto some company or other.

Arty skill and experience is what an FOO needs for fast calling. Experience comes from surviving battles and any kills he personally makes - arty experience from calling fires. Don't bother attaching an FOO unit to anything. Just buy one as B0 and let him do his thing.
