If surplus hardware from the 80s and 100 Bradleys have done what they have done imagine what 1000 Bradleys hundreds of we'll supplied and maintained Abrahams, Leos and Challengers can do when supported by the good ATACMS, Tomahawks and of course hundreds of F16s, F22s and F35s.

Or Ukraine with their kamikaze Cessnas.
