KANDAHAR AIRFIELD, AFGHANISTAN – There is nothing quite like coming off a patrol, your body-armor-shaped sweat stains still drying and ears ringing from grenades, only to have the hostess at T.G.I. Friday's tell you to wait a few. Sorry, sergeant, we've got to clear a table.

Or hovering over the desert for hours in a throttled-down Apache helicopter on an oh-dark-30 stakeout, disassembling half a dozen Taliban fighters with your chain gun as they plant a roadside bomb, only to get back to base and discover that the Canadian-themed doughnut shop is selling just coffee because insurgents blew up the latest inbound shipment of doughnut mix.

What's a man gotta do to get a maple-glazed in this war?

Soon enough, he won't be able to. The Kandahar Airfield boardwalk, for a decade the surreal yet comfortingly familiar heart of the biggest NATO base in Afghanistan, is closing down.

The festive, elevated rectangle of shops and fast-food vendors built around a small soccer field and running track will inevitably live on in the war stories of tens of thousands of U.S. and NATO troops and contractors who have lived at Kandahar Airfield or passed through it on the way to smaller combat outposts.

The businesses will shut down in phases, beginning next month, with the final one closing before the end of 2014, base officials said in an e-mailed statement. Most of the buildings will be torn down, though the walkway and the sports facilities will remain for a while.

The closure plan mirrors the withdrawal of U.S. troops as the NATO coalition here shrinks in advance of ending its combat mission next year. The 62,000 or so U.S. troops still in Afghanistan are expected to begin leaving in significant numbers after this year's summer fighting season tapers.

"This is a natural evolution as we draw down forces across the country," U.S. Air Force Brig. Gen. John Dolan, the base commander, said. "As our personnel numbers decrease, so will the amenities at our installations."

Every large base here has amenities to make long tours of duty more bearable, including "local national" markets, with cheap rugs and jewelry, bootleg DVDs, counterfeit watches and other goods and souvenirs. But they are all lowly five-and-dimes to the boardwalk's Mall of America-like grandness, street-corner buskers to Liberace.

Soldiers slurping tea and fruit smoothies browse locally owned shops that offer alterations, patches for uniforms, shoes, flat-screen TVs, cellphones, jewelry and carpets. They line up for American, Mexican, Asian or Middle Eastern fast food, or opt for dine-in at the T.G.I. Friday's.

Once there was a franchise of the famous-in-Canada Tim Hortons doughnut shop, though now it's run by a local owner under the name Coffee Time. The French exchange store also changed hands and names, though it still offers perhaps the only chocolate croissants in southern Afghanistan.

Soon, though, the croissants will be gone, and with them the hot dogs at Nathan's Famous, the rugs with AK-47 designs, the $700 jackets at the German exchange just like SEAL team operators wear, and, heaven forbid, even Gyros for Heroes.

The boardwalk. Famous and infamous. If the war in Afghanistan ever gets its own "Apocalypse Now" film treatment, the movie crew will have to rebuild it for that symbolism-freighted scene about the dizzying gulf between the two cultures fighting the war. KFC vs. whatever the Taliban outside the base are eating.
