note - if an expanding rod warhead detonates at a range greater than the maximum radius of the expanding rod 'hoop' (after which the hoop breaks up into individual elements), then it gets harder to tell the difference on one piece of wreckage. A blast frag has a larger spread widthwise than an expanding rod. a few pieces of damaged wreckage from different extremities of the aircraft will confirm blast frag.
