Conclusion

    Any military force in the world, especially one with the production capabilities behind it such as the Unites States, should take the protection and wellbeing of servicemen as an extremely high priority.  Much happens out of necessity in war, but sometimes corners are cut by the ignorant that could not care less what others say, regardless of having a worthwhile argument or not.  Just as modern U.S. infantry units should not be armed with only the M9 Beretta as it would get them all killed in any sort of ranged engagement, the U.S. tankers of the Western Front in WWII should not have been sent into action with a short barreled 75mm that was woefully inadequate against modern German armor, but they were.  There are many out there who divulge into petty arguments about the logistics of moving heavier armor across the Atlantic (after the U-boat menace had been all but subdued and U.S. ship production was still explosive) and the idea that you have to break some eggs to make some omelettes, but they all lack the empathy that should be given to the men that have to sit in steel coffins and fight for their country.  In truth, many American tankers died needlessly in WWII, and though so many lessons were learned in blood, it seems hard for the U.S. to learn from them.  The U.S. knew as early as 1994 that the Hummvee needed serious armor upgrades if it was to adequately protect troops, but through wars in Iraq and Afghanistan, many U.S. service members also died needlessly due to lessons learned in the past.
