The RAF campaign is highly accurate and is believed to have resulted in zero civilian casualties in the battle. Traditionally you would weigh up the civilian death toll with the strategic importance of eliminating the target. The RAF has taken a stance that if civilians are seen in the area the mission is aborted.
Our Tornado aircraft that both Germany and ourselves operate are relatively unique as an highly accurate and agile bombing platform and our brimstone missiles are second to none. They are incredibly accurate but expensive and there were reports we almost ran out recently.
Russia is being deliberately less accurate with its bombing but has turned its attention on the oil supplies which seems to be our mission at the moment. The U.S is bombing on such a larger scale that civilian casualties may be harder to prevent.
Do realise this though. The accounts of thousands of woman and children dying as a result of the air campaign being posted on Facebook are not true, not even close to it. Most of the air campaign is being carried out in areas where the civilian population has long since left or was never present (oil fields etc). Where they can be affected (such as civilian drivers of oil tucks), leaflets are dropped warning of the impending bombing giving them a choice. All of the above occurs with 'eyes on' the target throughout from drones etc.
