After receiving a BA in classics from Dartmouth in 1999, Nathaniel Fick passed the US Marines officer training course and joined the Corps just before 9/11. He saw action in Afghanistan and Iraq in the elite First Recon Battalion (the Marines' equivalent of the Navy SEALs or British SBS). Among the first US soldiers to enter Baghdad in the Iraq war, he left the service after being promoted to captain. He is now in a joint degree programme at Harvard Business School and Kennedy School of Government.
