Part 3 D-Day

I just read part 3 of the prologue of d day and I definitely agree with mr. Ambrose, especially when he said that mathias and brotheridge are one of he primary reasons for our freedom. What they did, I cannot even comprehend. How they volunteered to jump out of planes with 30% chancE of surviving. And I don't understand how the allies could train eighteen and twenty-eight year olds and expect them to just go out and fight. And without even training them as professionals. I am guessing that these men also became terrified and unable to fight once they saw their friends get shot. Which, for most of them, was the first time! I really thought that the allies did fairly well against the attack but I think if they took better precautions they could have done better.
