Thanks for posting this, I had not heard about it. I do have a few heroes that I would like to see considered- Chris Kyle, Pat Tillman, Rush Limbaugh, and Johnny Cash.
In addition to my four original suggestions ( Chris Kyle, Pat Tillman, Rush Limbaugh, and Johnny Cash ) I feel that I need to add one more- John Moses Browning, one of the top heroes of the USA. I wonder about the possibly different outcomes of WWI and WWII without Browning’s inventions.
