The answers address three issues: what the UK will do to reduce civilian casualities, what weapons are being used and ensuring "deconfliction with Russian operations in Syria." Here's what the MoD has to say on that last topic:
How will you ensure deconfliction with Russian operations in Syria?
British aircraft have already been flying combat missions over Iraq as well as reconnaissance missions over Syria. All these missions are co-ordinated by the US-led air operations centre and subject to safe separation measures.
