A report issued this month by the Institute for the Study of War says the number of soldiers in the Syrian military has fallen by more than half since the start of the conflict, from roughly 325,000 to 150,000, because of casualties, defections and desertions. Combat fatalities alone have surpassed 44,000, according to the report, which used data from Syrian activists, monitoring groups and media reports. Christopher Kozak, a Syria analyst at the institute who wrote the report, said that reservist mobilizations and efforts to stop desertions appear to be partly related to the departure in recent months of pro-regime militiamen. Scores of these largely Shiite fighters, who come from Iraq, Iran, Afghanistan and Lebanon’s Hezbollah movement, left for Iraq in the summer to counter an offensive by the Islamic State. The Assad regime has intensified efforts to reverse substantial manpower losses to its military with large-scale mobilizations of reservists as well as sweeping arrest campaigns and new regulations to stop deserters and draft-dodging.The measures have been imposed in recent months because of soaring casualties among forces loyal to President Bashar al-Assad, as well as apparent increases in desertions and evasions of compulsory military service, analysts say.
