Will BPL have the same effect on military radio as it has on radio
hobbyists? Don't they have spread spectrum capability which is highly
resistant to interference?

Spread-spectrum is highly resistant to narrowband interference. BPL
develops wideband interference. What the military depends on is the
physics that any remote jammer trying to create wideband noise would need
to be immensely powerful, because a wide band of loud-at-a-distance noise
would have to have substantial energy at every frequency. BPL defeats
this by putting the transmitting antenna very near the receiver, so the
noise source need not be powerful to be loud at every frequency.
