The photograph displayed below is genuine and shows Warrant Officer 1 Brook Turner tending a plot of grass with a pair of scissors at a military post north of Baghdad.  The picture was taken by Staff Sgt. Mark Grimshaw in mid-July 2004.
 

According to the Salem Statesman Journal:   [Turner] asked his wife to send him some grass seed because he missed the green he was accustomed to in Hawaii and before that in Oregon. Kim Turner was happy to send her husband a little slice of home. She bought a packet of grass seed and a small hoe and mailed them with other goodies in a care box. Brook prepared a spot behind the single-wide trailer he shares with a few other soldiers, lining the 3-foot-by-7-foot area with large rocks and adding some dirt. Photo from Snopes.com

As soon as the seed arrived, he planted it. He knew keeping the seed moist would be a challenge in the 125-degree heat.  His fellow soldiers teased him about his failed project, but he was determined to grow a patch of grass. He talked with some Iraqis civilians authorized to be on post, and arranged to buy some sod. He purchased seven 1-foot-by-3-foot patches.  Turner watered his lawn three times a day. He used a 5-gallon jug he filled in the bathroom, where the camp has running water.

Planting plots of grass are just one of many ways soldiers decorate their tents at other arid U.S. military outposts in the Middle East, including this example of a similar grass plot grown alongside a tent at Al Udeid Air Base in Doha, Qatar:

A former staff sergeant with the United States Air Force wrote to tell us:

The grass patch [just above] is located at the recently declassified Air Force base in Qatar, known as Al Udeid.  I lived three months of my life (fall of 2002) two tent rows from that grass.  It was the only grass on the whole base, and though I don't know who planted it originally I do know that the soldiers who rotated through that tent each became caretakers of it.  They watered it from their water bottles, trimmed the grass with scissors (as seen in the photo) and kept it shaded in the summer with a tarp awning over the front of the tent (many of the tents had such awnings, but this tent had a more elaborate one while I was there) to protect it from the 135+ degree summer sun.

The grass is real, and really is a comment on how we (US soldiers) work to make the best of things when we deploy in defense of our country and your freedom.
