Debka File is ,,,,not reliable.
It exaggerates for dramatic effect but its purposes are to scare Israel’s enemies and create sympathy among its friends, IMHO.
I call it propaganda and disinformation in support of Israel, a traditional tactic of war.
This report in particular is designed to create a new sense of what the war in Syria is about that subtly points out Russia’s actions to help Assad are not always in Israel’s best interests.
