I read a book about the "Tunnel Rats" that fought in Cu Chi against their VC counterparts...
That was an interesting and terrible story.
Tunnel Rats were servicemen who were chosen, by size, to crawl into the tunnel openings with only a .45 pistol and a flashlight to try and engage the VC that ran in the tunnels.
Because the VC were smaller in stature, they only excavated tunnels large enough for them to get thru, most Americans were too large to fit, so the
job went to the smallest soldier.
There were booby traps, enemy soldiers, water, animals and insects they had to endure. They also had a rope tied to their ankles, so if they were injured or killed, their buddies had a way to get them out of the tunnels.

The Viet Cong were also very resourceful as they tunneled in the area.
There was one story of a tank that was buried in the ground and used as a fortified 'bomb shelter'. There were also command areas, hospitals, storage areas and sleeping quarters for the fighters that spent weeks and months at at time living in the tunnels.
If you like interesting stories about war and history I recommend it highly
