Sorry, but if phasers can hit a shuttle moving at impulse speed - tens of thousands of kilometres a second - they're not going to have any problems hitting a vehicle moving along the surface of the world.
An armoured or heavily armed shuttle hugging the ground would possibly be a threat to ground forces...but it is simply a sitting duck to something in orbit.
Stunning? Who's talkinga about stunning? I'm talking about vaping a battalion at a time! 
Transporters can be stopped in numerous ways, which I pointed out in my original post. The rub is, however, that it can't be done over a large area.
Sure, you can hide out in mountains lined with kelbonite. Terrific. Let's assume I'm the Dominion, and you're the Federation defending Betazed. I've destroyed your starships in the system.
You have, say, a million ground troops.
I have, say, 10,000 Jem'Hadar. I want to capture government facilities, communications nexi, power distribution grid nexi, etc.
Now stop me.
Go ahead
Show me a way you could prevent me taking those areas. Remember that transport inhibitors and shields are localised. You can protect small areas, maybe even up to a kilometre or so in diameter with them.
For my part, I'm going to sit in orbit and scan for signs of shield use or transporter scattering fields. When I find them, I'm going to hit them with concentrated phaser fire and photon torpedoes.
Once this is done, I'm going to pick out the key locations I need to capture and scan them at high-resolution. As soon as I detect weapon signatures, I'm going to beam the individuals up and scatter their molecules into space.
Then I'm going to beam down teams of around 100 troops to secure each location. If there is any resistance, the troops on the ground will provide local defence, while my phasers carve up any approaching forces from orbit. Any vehicles approaching the location will be vaporised.
Now...how are you going to defend?
When you are dead, you don't know that you are dead. It is difficult only for others.
It's the same when you are stupid...
