Where in the World is Mike?

Mike is part of the 1st Battalion, 5th Marines (1/5). More specifically, I believe he is working with Bravo company, though I could be wrong on that. All the news reports indicate that the 1/5 is operating in the Nawa-I-Barakzayi District of Helmand Province, Afghanistan.

Photos of the 1/5 via Yahoo  (I' haven't seen a photo of Mike yet, but this Marine, Cpl Brian K, gives an idea of what it must have been like for Mike carrying the Mortar gear)

Taken from Wikipedia entry: http://en.wikipedia.org/wiki/Nawa-I-Barakzayi. According to Wikipedia, Nawa-I-Barakzayi District is located south to the Lashkargah District in Helmand Province, Afghanistan. The villages are located along the rivers, where the irrigation is possible. The drought has affected this district also, especially the number of livestock. The population is 79,100 and 99% of all inhabitants are Pashtun, with 1% of the population consisting of other ethnic minorities (Hazaras and Balouchis). The district center is Khalaj. Health care and education need improvement..

The Afghanistan Information Management Services (AIMS) has many maps.

Here is a more detailed map of the district and Helmand (Hilmand) province:
