With the arrival of the 12th anniversary of 9/11  and the war on terrorism a constant - not to mention the threat of a conflict with Syria, the war in Afghanistan and a continued U.S. military support role in Iraq - it's no wonder the most stressful jobs for 2013 are in our armed forces.

It’s worth revisiting CareerCast.com’s annual list of the most stressful jobs, which gives the No. 1 and No. 2 spots to enlisted military personnel and military general, respectively. The occupations were given stress scores on a 100-point scale.

CareerCast said enlisted personnel, who had a jobs rated stress score of 84.72, not only face the dangers of combat when deployed, but they also may have other stressful assignments, such as helping with natural disasters, and they face the stress of trying to re-enter the civilian work force. Their median salary is $41,998 for an E-7 with eight or more years of experience.

The military general, meanwhile, has the stress of dictating tactical strategy that may put enlisted personnel in harm’s way. The military general – the median salary is $196,300 - had a stress score of 65.54.

Rounding out the Top 10 and their stress scores were (3) firefighter (60.45); (4) commercial airline pilot (60.28); (5) public relations executive (48.52); (6) senior corporate executive (47.46); (7) photojournalist (47.12); (8) newspaper reporter) (46.75); (9) taxi driver (46.18); (10) police officer (45.60).

New York firefighers suffered heavy casualties during the terrorist attack on the World Trade Center 12 years ago. Of the 2,753 people killed  in New York, 343 were firefighters and paramedics, while 60 others were NYPD and Port Authority officers.
