In brief, Sniper Elite: One-Way Trip involves Navy Seal, Gil Shannon -- one of America's most lethal snipers -- who, in defiance of the president, launches an almost impossible mission comprised of Seal Team Six and Delta Force fighters to free a female helicopter pilot being held captive by Taliban insurgents in Afghanistan.
On the positive side, Sniper Elite: One-Way Trip is a very fast-paced, gripping military thriller that is packed with non-stop action. The military action scenes will make you feel you are right there in the middle of the mission. Further, the authors do a good job in conveying their viewpoint (with which I agree) on the selfless service provided by our Special Forces versus the (at times) more selfish, personal, political interests of the President and other high level bureaucrats.
These positives, however, are offset somewhat by what I considered to be some unbelievable exploits of the main character, Gil Shannon, who comes across as so larger-than-life that he seems invincible. This opinion stems from his ability to be a non-stop killing machine despite encountering multiple, simultaneous serious injuries -- any one of which would likely stop a normal person. Further, while I found Shannon's salty manner of speaking with his fellow soldiers to be credible, I had a minor problem with how he developed a John Wayne-like manner of speaking when talking to his wife and women in general. That is, I found his attitude to be a bit too deferential, bordering on being condescending. For example, don't all men when engaged in conversation with their wife refer to her as "ma'am"? As a result of these factors I have deducted one star -- 1 1/2 stars if Amazon allowed it -- from my rating.
If you think you would not be bothered by what I mentioned as offsetting factors, than I think you will enjoy Sniper Elite: One-Way Trip very much.
