And for the second questions; most identification is done visually; just as armor crews and pilots in militaries are trained to identify vehicle silhouettes, FRAME pilots are as well. A radar might show a FRAME-sized blip, but to understand what model it is, and what sort of armaments it has, the pilot ought to get a true visual. Once he does, however, that info can be relayed to other teammates and inputted into his databank for reference.[/quote]

BTW, it IS possible, [i]with training[/i], to determine what sort of movements the radar-contact is making, [i][url=https://www.youtube.com/watch?feature=player_detailpage&v=Xb9je-NHAWs#t=1117]purely on their Doppler-shift[/url][/i].

-As the contact likely sounds like a very big clunky person, training to determine walking, running, crawling, and sprinting between cover are actually things people are trained to do, [i]even if the radar-contact is brief[/i] they will have a rough idea of their pace, tempo, and wariness.
