No army is equipped to fight a land war in today's world. China could potentially mobilize enough industry to equip an army that way, but they don't really have anyone to fight that way.
Other than that, every single modern war depends on air superiority as an absolute requirement. You destroy the enemy before any of your guys are on the ground.
But you absolutely cannot do that against modern integrated air defense without losing a sizeable portion of your planes and pilots, which are too expensive to risk.
It's not just that.
