"I mean, you got to do the training… I think that we’re talking about weeks," Mattis said. "I don’t know how many. Two, four, six, but I don’t think we’re talking months."
"It’s already happening on opposite sides where the two of the patrols go along, and they get to certain points, they wait for the other one to get there," Mattis said. "If somebody gets there first and then they do recognition signals back and forth and they move onto the next one."
Mattis explained all the conditions for establishing joint patrols are being set for them to go forward, and the Turkish and US militaries have put together all the planning while the training equipment has landed at the Incirlik air base in Turkey.
"I can’t give you a hard and fast timeline, but it’ll be good training. Both on the Turkish side and on the Coalition side, we agree that this is necessary to make sure that what we do with these patrols is stabilize the line and not inadvertently rush forward into it and you don’t have trained people, so it’s going very, very well," Mattis said.
The Syrian government has repeatedly stated that the presence of Turkish and US forces is a violation of Syrian sovereignty. Neither the United States nor Turkey have obtained a UN Security Council mandate to operate in Syria.
