What does (generals) mean in this context?

Kushner also denies reports he discussed setting up a secret back-channel with the Russian ambassador to the U.S.
He said he did speak with the Russian ambassador, Sergey Kislyak, in December at Trump Tower. But he says that conversation was about policy in Syria.
Kushner says that when Kislyak asked if there was a secure line for him to provide information on Syria from what Kislyak called his "generals," Kushner asked if there was an existing communications channel at the embassy that could be used. Kushner says he never proposed an ongoing secret form of communication.
