Would Russia use battlefield tactical nukes to destroy Ukrainian forces on its own land?

You read the headline.

I think its possible.  It would stun and frighten the West and yet NO ONE COULD PLAUSIBLY do a thing about it.

They used tactical nukes on their own land against an enemy force.

How do you justify attacking a country for nuking its own land? NATO would be on the sidelines.  The US could posture but in the end do nothing.

The only real question, because I'm sure its been considered is if its worth it.

Do the Russians have neutron bombs?  High radiation levels that should rapidly dissipate if I remember correctly.  This sounds almost tailor made especially since structural damage would be limited.

What do ya'll think?
