And by December, the US said 97 percent of ISIS-held territory in Iraq and Syria had been liberated, and Iraq declared its war against the group over.
At the moment, there are about 750 militants in Al-Shaddadah and 350 in Al-Tanf on the Syrian-Jordanian border, according to Gerasimov, who said the Russian military has been watching the training at the Al-Tanf base for some time.
But he later clarified the coalition would only defeat ISIS "in areas controlled by partner forces", leaving the Syrian regime and their Russian backers to oust the ISIS fighters that have moved west.
USA officials have said in the past that the Syrian government forces are too few, too poor and too weak to fight ISIS. The unrest in Syria allowed ISIS, the self-styled jihadist extremist group, to control parts of the country, but the group has now lost nearly all of its territory.
"Thus, during the battle for Deir ez-Zor, for other settlements in the Euphrates River valley, the use of vehicle bombs have reached nearly a mass scale", Gerasimov said.
"They are practically Islamic State", the general said.

He was also involved in the grenade attack carried on State PWD Minister Naeem Akhtar's cavalcade in Tralon 21 September. Meanwhile, the forces in Kashmir have been successful in neutralizing over 10 of the JeM terrorists in past few months.
According to an account by Reuters of Gen. Gerasimov's interview Wednesday, the general claimed those being trained at Tanf are actually former Islamic State militants who now call themselves the "New Syrian Army," among other names. "They are tasked with destabilizing the situation".
Washington has rejected similar Russian allegations in the past, saying US forces remain committed to killing off the Islamic State and denying it safe havens.
Iraq and Syria have both declared victory over ISIS in recent weeks, after a year in which the two countries' armies, a range of foreign allies and various local forces drove the fighters out of all the towns and villages that once made up the militant group's self-proclaimed caliphate.
Despite saying that the Syrian government is not doing enough to stop ISIS militants from moving through its territory, the US-led coalition fighting the group does not intend to target militants in those areas, a senior coalition official said on Wednesday. The U.S. had focused its forces in Syria on destroying ISIS since the group came to prominence in 2014.
The United States has led an global coalition conducting air strikes against Islamic State since 2014 when the group swept across a third of Iraq.
Mr Assad's main ally Russian Federation also said on Wednesday the main battle with Islamic State in Syria was over.
