How did Japanese island fortifications seemingly bear American prep bombardment from naval guns and planes dropping bombs? Can a few feet of earth and a few inches of concrete really be enough to save you from an American shell? I suppose the same question applies to Vietnamese tunnels in the late 60s, German dugouts in the Great War, and Iranian mountain lairs today
Yes. Tunnels are the most OP defensive strat in the history of mankindNext question.
>>65610850It's not a few feet, it's many feet. Dirt/soil/sand can cushion a blast through reverse granular impact. Think of what a sandbag can do and scale it exponentially. Solid natural rock can have different properties depending on what kind, but generally if it's thick enough there isn't any ordinance available to punch through it. Even bunker busters specifically designed for the task have limits.The best bet is to hit the entrances and seal the place in assuming you know for sure where every entrance is. If it's not deep enough you might also cause some cave ins, but there's no way to know from the air that you have truly taken out the entire complex.This is why when Trump admin took a shot at that Iranian nuke facility a few months ago they didn't just drop bombs on top of it. They blew the entrances in and hoped it would get the job done.
>>65610883>They blew the entrances in and hoped it would get the job done.Cant they just dig a new one in the same place or elsewhere, in due time?
>>65610850Some of the mid-era bombardments in pacific theatre ww2 calc'd out to about a shell per square meter and did almost nothing. You've seen the WW1 aerial photography too, right? These bombardments were what stimulated the conclusions of 20th century conventional warfare. It's economically nigh-impossible to beat dug in forces through bombardment using dumb conventional weapons. The effective way is only bombarding a little, to pin the enemy down, and then sending ground troops to flank them/dig them out.
>>65610880>Tunnels are the most OP defensive strat in the history of mankindDo the US have any tunel network? Or it is only avaliable to plucky resistance and underdog in war?
>>65610945The US has strategic depth. In American Revolutionary War, this is what the rebels/Patriots/Continental Army/whatever they were called in common parlance, utilized after suffering defeat at the hands of King George's men
>>65610919That's pretty much what they did, yes.
>>65610850>A few feetI encourage you to read up on Iwo Jima's tunnels.
