The New York Times reported last week that “Saudi Arabia has financed a large purchase of infantry weapons from Croatia and quietly funneled them to antigovernment fighters in Syria.” The effort was reportedly known to the US, but nothing was said for or against it so that it might proceed under the radar of a European Union arms embargo on Syria.
Palettes of former Yugoslavian weapons are not game-changers in and of themselves, and the way they’ve been secured by the rebels shows that the US still refuses to place its bets on any specific group. That said, the arrival of planeloads worth of small arms is significant in that it demonstrates a greater investment in the rebels by their foreign backers. According to the Australian small arms expert Nic Jenzen-Jones, it is the quantity of the weapons that is the most significant development for the rebels: “a lot of people are discussing, ‘is x system effective against y armoured vehicle?’. What’s more important in this conflict is that we’ve seen an initial dearth of weapons and only recently have we seen supplies of anti-armour weapons significantly increase.”
“It’s a long term thing, but I’m sure we’ll see the situation in Daraa look very similar to that in Aleppo in the coming months,” the Times’ Eliot Higgins told me, as Aleppo and other parts of northern Syria are falling under rebel control due to the capture of multiple Syrian military bases in the region. According to Higgins, the new weapons have given the rebels an "extra edge that has allowed them to start attacking checkpoints and bases, resulting in the capture of heavier equipment” from the Syrian Army.
Jenzen-Jones explained that three types of Eastern bloc anti-tank weapons – the M79 “Osa,” the M60 recoilless gun and the RPG–22 – now in use in Syria are “suitable for the type of hit-and-run urban warfare the rebels are conducting.” Suitable, but not “game-changing.”
