Sgt. Bob Pyatskowit says his troops are welcomed here.
"They actually like us around for security reasons," he says.
One man says he's going to vote, because he's counting on the new president to give him a home instead of the tent he's living in now.
As CBS News Correspondent Lara Logan reports millions across Afghanistan have signed up to vote, even in areas once hostile to American troops, like the town of Asadabad.
Two years ago the idea that people in a remote rural area would be able to go to the polls and vote in a national election was unthinkable. But today, some 96 percent of eligible voters in this province have registered, showing their determination to have a say in Afghanistan's future.
American Special Forces have helped Afghans transform this town. The main road's now paved, business is booming, and girls are back in school after being banned under the Taliban.
The U.S. paid $5,000 to repair one school, where the teachers said they all registered to vote, as did their wives.
Sgt. Galen Lewis said there's great support for the election.
"They're excited. They show you their registration card, which is a big deal for them," says Lewis.
Despite the enthusiasm, security is an issue, with 12 election workers killed this year.
To ensure the elections can take place, "We help the Afghan security forces with equipping issues, vehicles, providing arms and ammunition and training," says Lt. Cmdr. Doug Marrs.
American and Afghan security forces are braced for attacks on polling day but say that will not stop the election.
