For whatever reason, military GPS signals are very special, and
give position in inches, which the civilian codes don't.

Then again, the Soviet don't yet have a credible ASAT capability,
what they have is crude and slow, until the laser gets a bit
hotter, or unitl they mine space.

Then again, the Soviets might not even get a chance to KO the
satellites, in a U.S. first strike.  I was given to understand
that GPS was a planned assist for Trident missiles, and it is
not difficult to believe it would be implanted in future ICBMs.
