Dumb munitions had limited tactical application in warfare. There is a shift from that to precision munitions which have considerable tactical application in warfare. Now anything on the ground can be struck with great precision from a distance. Iranian defenses are not in good shape after facing a large number of precision strikes since Feb 28, they have lost many equipment pieces, troops and experienced commanders. It is very difficult for them to gather in once place and not draw attention, some commanders did that and lost their lives. They have some operational underground bases but these cannot help stop a special forces raid like an army out in the open which is exposed to air strikes.
Wars have panned out differently historically and even recently, it comes down to planning, tactics and tools used. Iran wasn't subjected to massive bombing during Operation Eagle Claw, it was a small-scale infiltration move that failed due to limited planning and an accident. But the US is learning from its past experiences. The ongoing Operation Epic Fury is of entirely different character in execution and scale. They are creating conditions suitable for special forces raids and possibly more on the ground.
Let's see what happens.
