I would like to elaborate on Question 5.
Personally, I wonder how any progress was made in WWI. In a scenario dominated by trench warfare, why was each side not desperately developing new technology? If one side recieved the order to go on the offensive, they charged, the men knowing that it would be their end. The majority of the soldiers followed orders to the death. When they approached the enemy's front, they were shot down by machine-gun-equipped men hiding in trences. If by some miracle they made it past the first line, they found a second, even a third. They were at an impossible stalemate. I feel like it should have been number one priority to develop the technology to overcome this deathly obstacle, and that millions of lives were lost in vain.
