Direct proof of use
MILAN use in the Syrian Civil War is directly documented at Kobane. Conflict Armament Research reported that Islamic State forces used MILAN anti-tank guided weapon systems in the city, and its field investigators photographed European MILAN materiel in Kobane after the battle.
The same CAR dispatch states that its team worked with Kurdish People's Protection Units (YPG) between 20 and 27 February 2015 to document weapons the YPG had captured from Islamic State forces. CAR framed the Kobane sample as physical evidence from the September 2014 to January 2015 siege rather than a complete chain-of-custody record.

Kobane siege context
The documented MILAN case belongs to the Islamic State offensive against Kobane, a northern Syrian border city defended by Kurdish forces during the wider Syrian Civil War. CAR's public dispatch describes the report as an analysis of weapons and ammunition captured from Islamic State forces during the siege from September 2014 through January 2015.
CAR grouped the MILAN with other advanced anti-tank weapons observed in Kobane, while separately noting that both Syrian and Iraqi armed forces reportedly held MILAN systems in their inventories. The report did not assign a final supply route for the Kobane MILAN materiel.

Battlefield role
In this conflict-use record, the supported role is anti-armor use by Islamic State forces. CAR identified the MILAN as an anti-tank guided weapon system and treated it as one of the more sophisticated guided weapons found in the Kobane evidence set.
The record does not treat mere Syrian or Iraqi inventory holdings as proof of a transfer route. The source-backed claim is narrower: Islamic State forces used MILAN systems in Kobane, and CAR later documented the captured materiel in Syria.
