What is Resolving forces: Definition and 36 Discussions
Operation Inherent Resolve (OIR) is the U.S. military's operational name for the International military intervention against ISIL, including both a campaign in Iraq and a campaign in Syria, with a closely-related campaign in Libya. Through 18 September 2018, the U.S. Army's III Armored Corps was responsible for Combined Joint Task Force – Operation Inherent Resolve (CJTF—OIR) and were replaced by the XVIII Airborne Corps. The campaign is primarily waged by American air forces in support of local allies, most prominently the Iraqi security forces and Syrian Democratic Forces (SDF). Combat ground troops, mostly special forces and artillery, have also been deployed, especially in Iraq. 75-80% of the airstrikes have been conducted by the military of the United States, with the other 20-25% by the United Kingdom, France, Turkey, Canada, the Netherlands, Denmark, Belgium, Saudi Arabia, the United Arab Emirates, and Jordan.According to the Pentagon, by March 2019, the day of the territorial defeat in Syria of the Islamic State of Iraq and the Levant (ISIL), CJTF-OIR and its partner forces had liberated nearly 110,000 square kilometers (42,471 square miles) of land and 7.7 million people from ISIL, the vast majority of the self-proclaimed caliphate's territory and subjects. By October 2017, around the time of ISIL's territorial defeat in Iraq, CJTF-OIR claimed that around 80,000 ISIL militants had been killed by it and its allies (excluding those targeted by Russian and Syrian Air Force strikes). By the end of August 2019, it had conducted 34,573 strikes. Tens of thousands more were killed by partner forces on the ground (the SDF alone claimed to have killed 25,336 ISIL fighters by the end of 2017).
Hello all, I am sadly stuck on the last part of a circular motion question sheet I was given for homework. I have a mark-scheme with me, but it has actually given me more questions than answers. I have attached my working, and how I arrived at my answer, and the differences it has with the...
I need help with the following question please.
