The prime beneficiaries of cash and weapons from Qatar are increasingly the best armed and most organised of the myriad opposition units trying to oust the Assad regime. But they are increasingly at loggerheads with other elements of the opposition, especially those who brand themselves as moderate or secular nationalists.
The Farouq Brigade, a fighting force that emerged from Homs, is the best armed in the country, thanks in part to the supply of weapons it has received through Lebanese MP Orkab Sakr, who is aligned to Lebanese opposition leader, Saad Hariri, and worked on behalf of the Saudis until recently.
The Liwa al-Tawheed Brigade, one of the first into Aleppo city in late July, has also received Saudi help, but has recently looked more towards Qatar.
Syria's Muslim Brotherhood movement is also backing several Islamist groups.
Foreign "Jihadists"
With the exception of those arriving from Iraq, the foreigners are almost all turning up without weapons or ammunition. Many of those who have travelled to Syria since July have extensive experience from fighting US and government forces during the Iraq insurgency.
They are increasingly being deployed to frontline areas in Aleppo and linking up with hardline elements among the Syrian Islamists. There is evidence of some of the new arrivals joining forces with the main Salafist jihadist group, Jabhat al-Nusraf. There is speculation that the time for the foreigners to start conducting their own operations is near.
Opposition Military Council
The group of senior military defectors who have largely remained in exile in Turkey has received little in the way of weapons from any foreign patron. They have, however, been the main contact point for western intelligence agencies, including the CIA and Turkish intelligence, who have supplied communications equipment and tactical advice.
They have received cash from Saudi Arabia and Qatar, which they are then allocating to regional councils to buy weapons from arms traders.
The council is struggling to establish a chain of command and control within the Free Syrian Army, which is heavily fragmented and unable to function as a standing military in all but a few areas. As a result, council leaders have crossed into northern Syria to establish bases. They have no shortage of funds, but resentment over the limited role they have played so far means they are struggling to win the respect of the units and villages they are visiting.
