Oh, you
will see a giant monster stomping a city and shrugging off massive volleys of weapons fire in shin godzilla, absolutely.
In fact the scenes with the military going at godzilla are extremely well done and more believable than any other kaiju film I've even seen.
You see, in the movie they aren't just throwing fireworks at a rubber suit ramdomly. It's assumed a trained, competent, modern military can actually reliably and consistently hit a target that is many, many times larger than anything it's been trained to engage for years, and is moving fairly slowly.
How many times have you shouted "Aim for the damn head already?!?!" at the incompetent militarys in other kaiju films who seem to miss godzilla with 90% of what they fire at him? In shin godzilla the weapons fire looks quite realistic, and they actually seem to hit him at least 99% of the time, and they indeed aim for and hit the head. We see realistic military vehicles attacking godzilla including gunships, tanks, artillery, fighter bombers, etc. Wow, you mean a professional, trained and well equipped modern military can atually reliably hit a target dozens of times larger than it was normally trained to hit? Amazing!

It's just that people fairly quickly realize that conventional military forces aren't going to stop this thing. (One attack comes close) and act in an intelligent fashion. A military commander, realizing they can't kill this thing after expending their ammo loadouts against it, orders his men to focus all efforts on speeding up the evacuation of the population to save lives. He tells his men that's the best they can do for their country now.
The military fights and monster city stomping are definitely there, and very well done. It's just that this movie does so much more than that.
