A militant group which opposes both ISIS and the Syrian regime has released a striking video showing off 1,700 troops, fleet of armored tanks and special forces soldiers in an impressive military parade. These men form a small part of Jaysh Al Islam - or Army of Islam - who reportedly command as many as 25,000 loyal fighters following the merger of up to 60 rebel factions inside Syria. Dozens of masked special units show off a range of skills including close-range combat in what the group claims is the 'largest military parade witnessed' since the dawn of the Syrian revolution in 2011. Jaysh Al Islam is led by Sheikh Zahran Aloush who addresses the thousands of armed soldiers and tanks once they have assembled on the vast concrete ground below.
