Problem:Passage: A Military Shield detachment was present at the Palmyra frontline in December 2016, when ISIL launched a large-scale offensive in the area. This unit was later accused by the Tiger Forces to have fled in disarray after the first serious Islamist attacks, leaving Palmyra and Tadmor's remaining pro-government defenders to their fate. Soon after, Palmyra fell to ISIL, and the Military Security Shield Forces were among the pro-government units that sent reinforcements to help defend the nearby Tiyas Military Airbase from the next Islamist attack. The unit was also involved in the following government counter-offensive in the area. On 23 February 2017, al-Masdar News reported that over 900 Syrian Marines had joined the Military Security Shield Forces in order to avoid being drafted into the regular army. In June 2017, the Military Shield Forces took part in an anti-ISIL offensive in eastern Hama. Later that year, the militia took part in the battle to retake all of Deir ez-Zor city from ISIL. Afterwards, Military Shield militiamen began to garrison towns in eastern Syria which had been retaken from ISIL, such as Mayadin. The pro-opposition Syrian Observatory for Human Rights accused the militia of requisitioning food from local civilians during this time.
