KABUL -- Secretary of State Rex Tillerson says the United States wants to force the Taliban to the negotiating table in Afghanistan. At a Tuesday press briefing, he contradicted President Trump's assertion that the administration's new strategy in America's longest-running war is about total victory.

Afghan President Ashraf Ghani thanked President Trump and the American people for their continued support here this week. At the top of the list, he mentioned the development of the Afghan Air Force.

CBS News correspondent Charlie D'Agata recently got the rare opportunity to watch U.S. fighter pilots training new Afghan pilots to wage war in Afghanistan's not-so-friendly skies.

The fleet they're being trained on doesn't necessarily resemble what most Americans would consider modern aircraft, but then, the Afghan military's long fight against the Taliban could hardly be described as a modern war.

Brig. Gen. Phillip Stewart tells CBS News the help in the air could just help the Afghan's break the stalemate with the Islamic extremist insurgents.

"This is a country that screams out for air power," Stewart said. "It doesn't have a whole lot of roads. It's mountainous."

That terrain suits the new Afghan fighter division, which consists of a 12 American-built A-29 Super Tucano planes and about two-dozen MD-530 attack helicopters, capable delivering a full payload, and equipped with heavy machine guns and guided missiles.

U.S. combat pilot Lt. Col. Johnnie Green is in charge of handling Afghanistan's "Top Guns," and he tells CBS News the aircraft are fully equipped with communications equipment to enable Afghan Air Force pilots to get targeting information directly from their own personnel on the ground, "all in their own language. That is all on them."

So is the maintenance. The A-29s, single-propeller planes, use the same kind of engines found in planes like civilian Cessnas, so they're easy to fix.

It says something about the level of security in the country that the Afghan pilots who spoke to D'Agata didn't want to be identified, but one said it was the Taliban who have new reasons to be fearful.

At first, the pilot said insurgents mocked what appeared to them to be long-outdated aircraft. But then they found themselves on the receiving end of one in combat.

"After that, they said, 'we should hide.'" Now, if a group of militants hear the growl of an A-29 engine approaching, they try to get to cover.
 
The planes are also capable of dropping laser-guided 500-pound bombs, which makes them both cheap and deadly.
