A man walks in front of a burning building after a Syrian Air force air strike in Ain Tarma neighbourhood of Damascus in this January 27, 2013 file photo. In a month on the frontline Goran Tomasevic documented rebel fighters as they defended a swathe of suburbs, mounted complex mass attacks, managed logistics, treated their wounded - and died. But as constant, mortar, tank and sniper fire attested, President Bashar al-Assad's soldiers, often just a room or a grenade toss away, were equally well drilled - and much better armed.
