Abu Yashar pointed out small bomb craters in his surrounding fields and displayed an unexploded mortar round that landed on his property. He also showed where artillery shells from the airbase slammed into his tractor and into a concrete shed.
"Everything the people need to survive is being targeted by the regime," the farmer said.
The airbase itself is a sprawling walled compound located not too far off a main road.
From amid the cover of tidy rows of olive trees that surround the installation, one can see with the naked eye at least three helicopters parked on the tarmac.
It was here in the olive groves that Abu Marwan and another commander named Abu Jelan had set up a telescope to spy on their enemy.
"The soldiers have started moving from inside the restaurant," Abu Jelan announced into a walkie-talkie, as he peered through the scope. He tried to call in sniper fire. "Guys, snipers! They're moving from the clubhouse to the west. They're running."
The two commanders were helping a rebel mortar team at another location target their attacks on the base.
Before every round of mortar fire, the fighters murmured a little prayer to each other over their radios.
After thunderous explosions, they tried to assess the impact of their attack.
"It landed 10 meters short of the wall," a man on the radio said after one mortar attack.
