In 2013 the CIA was handing out TOW anti-tank missiles to ‘moderate rebel’ groups who were fighting the government in Syria. These groups were allegedly ‘vetted’ before they receive money and weapons. Unfortunately ‘vetting’ was something the CIA had never been good at.
One of the groups that received such support was the Hamza Division:
Hamza Division (Forqat al-Hamza – فرقة الحمزة): An FSA-banner group composed of six substituent brigades that operate mostly in the environs of Inkhil, Daraa. The Hamza Division has received TOW ATGMs and it works under the supervision of the Daraa Military Council. They receives foreign support from Western and Arab state backers and are a member of the Southern Front coalition. The Southern Front has stated their commitment to a civil state, and have released a comprehensive political program in support of democratic reform. The Division came together with the Syria Revolutionaries Front and the 1st Artillery Regiment to create the 1st Army, which later disbanded. The Hamza Division continues using the 1st Army imagery alongside its own while the other former substituents do not. Social Media: YouTube; YouTube (older channel)
Hamza was later also supported by the Pentagon. Without such support the group would never have become a viable entity. Things got a bit complicated when militias armed by the Pentagon started to fight those armed by the CIA.
Later Hamza was sponsored by the Turkish state. This again made things a bit complicated:
Elijah J. Magnier @ejmalrai – 17:39 · Oct 16, 2019Do you remember when the #US spent $500 million to train/arm Al-Hamza Division?
Well the US-trained “Moderate rebels” are fighting – under a NATO flagged country (#Turkey) – the US-trained Kurdish YPG in the area occupied by the #US.
I’ll make it even easier: A few minutes ago, #US Prsdt @realDonaldTrump said the “PKK is far more dangerous than #ISIS (The Islamic State)”.
The US trained & armed Syrian Kurds proxies, the YPG, are the Syrian branch of the PKK that Trump considers far more dangerous than ISIS.
