WW2 Island Defenses

Hello, I just wanted to share some info on Japanese Island defenses even though a lot of people say that it wasn't craftily built. I kinda figured you'll all enjoy seeing some things they did use to defend with:
The Japanese mind set was primarily set on offensive, offensive is a good defense as some would tell you. But during the Island fighting they had to adapt to a new concept of fighting... defensive-offense. Normally it would include, but not limited to Trenchs, Spider Holes, Pit Traps, Gurella Warfare, Kamikaze, Banzai Charges, Caves, Bunkers, it continues on.
Many times they would not have a lot of concrete, steel, and strong wood so they would improvise by mixing sand or sea shells to make concrete, using palm trees as building material as well. They would in fact also use high ground and valleys to maximize their ability to cause heavy loss on the enemy.
They would also employ suicide such as faking a surrender and blowing themselves up to kill the enemy, Banzai Charges, and Kamikaze attacks.
That is a base summery, here are some pics now :
