What is a list of objects considered protected from military operations under international law?

The No-Strike List is indeed the correct answer because it specifically identifies objects that are protected from military operations under international law. This list may include cultural heritage sites, certain civilian infrastructure, and other civilian objects that should not be targeted to prevent unnecessary civilian casualties and collateral damage. The existence of such a list reflects the principles of distinction and proportionality enshrined in international humanitarian law, which aim to protect civilian life and property in times of armed conflict.

The other options, while related to military operations and target planning, serve different purposes. The Restricted Target List designates targets that require special consideration or restrictions due to their potential impact or sensitivity but does not necessarily categorically protect them from attack. Fire Support Coordination Measures are procedures and protocols for deconflicting fire support operations to avoid friendly fire and ensure that targeting is conducted efficiently but do not specifically designate protected objects. Lastly, a Collateral Damage Estimate assesses potential collateral damage resulting from planned military operations rather than listing objects that are protected from targeting.
