Probably...

I wouldn't.  I notice that the meson gun (battlefield) is also perfect
for mounting on a merchant ship for anti-piracy defense.  Sounds like an
idea to forget as soon as possible.  Based on the fact (?) that no meson
guns at TL14- are less than 650Kl, I suspect that the battlefield meson
gun is one of those things that Traveller introduced because it was a
"neat idea", not because it fit the system.

Which is a fine example of operating at altitude.  What is the max range
at sea level on those charts?  I get 19nm for an effective height of
19m, which is rather taller than most tanks.  This give a Pancake
diameter of 70.4Km.  A 5m tank should not be detectable at more than
25Km.

Sounds good.  A little weak against orbital fire, but quite effective in
the pancake.  It would also be weak in dogfights, since it's vulnerable
angles are large, but if you kept your enemies at long range, this
should not be a problem.

No.  Inertial Compensators are anti-Jerk fields (jerk= first derivative
of acceleration).  They produce a grav field which compensates
internally for changes in the local acceleration field.
