Taliban insurgents have stepped up suicide attacks and bombings this month in what they are calling a "Spring Offensive", striking targets all over Afghanistan. Insider attacks on NATO and Afghan National Army forces have declined, possibly due to new "guardian angel" tactics, where soldiers are designated to provide security during training and oversight missions. I'd also like to take a moment to direct your attention to Ben Anderson's Afghanistan documentary on VICE.com, What Winning Looks Like. If you're at all interested in what the situation is like in Afghanistan right now, this documentary is well worth the time, showing the good, bad, and ugly sides of the war as we approach the 2014 withdrawal deadline. The photos below are show scenes from this conflict over the past month, part of the ongoing series here on Afghanistan. A U.S. soldier arrives on the scene where a suicide car bomber attacked a NATO convoy in Kabul, on May 16, 2013. A Muslim militant group, Hizb-e-Islami, claimed responsibility for the early morning attack, killing many in the explosion and wounding tens, police and hospital officials said. Afghan air force 2nd Lt. Niloofar Rhmani walks the flight line at Shindand Air Base, Afghanistan, prior to her graduation from undergraduate pilot training, on May 13, 2013. Rhmani made history on May 14, when she became the first female to successfully complete undergraduate pilot training and earn the status of pilot in more than 30 years. She will continue her service as she joins the Kabul Air Wing as a Cessna 208 pilot. Marine Sgt. Ross Gundlach, of Madison, Wisconsin, gets a kiss from Casey, a four-year-old yellow labrador that he worked with while deployed in Afghanistan, as the two are reunited during a surprise ceremony, on May 17, 2013, at the Statehouse in Des Moines, Iowa. Gundlach thought he was traveling to the Iowa Capitol to tell state officials why he should take ownership of the dog, which has been working for the state fire marshal's office. Gundlach didn't realize officials already had made arrangements to get another dog for explosives detection.
