How is it possible that people use tunnels for military purposes?

For well over a century we have dug underground tunnels for the purpose of evading our enemies but that was back then, this is the 21st century.

Wouldn't a tunnel be an extremely bad idea, they have technology nowadays like sonar that can penetrate the ground and reveal the location of tunnels.

If you are conducting any kind of major project from underground wont that show up as activity on the surface?

The people working underground must have a source of fresh air, and food, water and supplies, if they have spy satellites watching the ground wouldnt that kind of suspicious surface activity really stick out?

Like if a bunch of people went into an area and suddenly disappeared wouldnt that be the prime location of where the tunnel entrance is?

There are so many disadvantages to being underground, if you were located and they cut off the air supply, or flooded the tunnels with water or poison gas wouldnt that be instant death to anyone inside?

Even if you didnt know the exact location of the tunnel and you drop some bombs in the area the shock waves going thru the ground are going to cause massive damage to anything alive in there? 

How do militia groups like Isis and Taliban hide away in tunnels without getting noticed?

    It is true that tunnels do have disadvantages, but they are still a lot more secure that having all your resources above ground.

    For example, bullets and shells generally cannot penetrate more than a few feet of soil, but they are effective against personnel and structures above ground. It takes a considerable amount of explosive in a very heavy container to penetrate earth or concrete and destroy anything deep underground. NATO forces use a length of heavy steel gun barrel with a calibre of around eight inches filled with high explosive for ground penetration, but these devices are very heavy for aircraft to carry.

    In WW2 the allies used "earthquake bombs" to eliminate much of the German underground "secret weapon" infrastructure towards the end of WW2. These bombs weighed about 10 tons each.

    Forces today have to attempt to evade detection by satellites. One of the best way to do this is to go underground. But it is not sonar which leads to detection, it is the difference in infrared emission from sites where there is underground activity compared to the surrounding areas which causes problems.

    Well if you were on the surface when a bomb dropped on you I expect you would die ! If you were in a tunnel or cave 100 m underground you would not even know they had dropped a bomb as you would be so shielded by the rock above you. There are natural caves all over the world and they really are bomb proof ! The Taliban can stock pile food and live in caves and tunnels for years with supplies being restocked whenever its safe to do so. Sonar etc can not scan deep cave systems and some natural pot holes and caves are 60 mile long with a network of tunnels that are unmapped. The Taliban could have lookouts and booby traps , explosives guns and defenses that they have spent months making so a surface attack would be difficult and not easy to do in a way that would surprise the Taliban. If it were easy then the Americans would have done it years ago.

    Tunnel under your house, put a nice big bomb in there, and make it so it goes off when you sit on the toilet.

    It worked very well in Viet Nam, not all that long ago.

    Underground can provide many advantages, The Taliban uses dried up underground well systems to move and evade coalition forces to this day.

    sonar absolutely cannot penetrate ground unless its extremely low frequency which isnt realistically used, no idea where you could have even come up with such a ridiculous and untrue claim
