What a medal can tell you
A medal gives you a quick indication of how the completed operation was judged. It can help you compare your own attempts and identify a run that was cleaner than an earlier one. It does not, by itself, reveal every hidden condition used by the game. Avoid assuming that one visible factor, such as speed or ammunition use, is the only reason for the result.
What is not safe to promise
There is no reliable public basis for publishing exact universal medal thresholds for every mission. Different operations test different skills, so a rule inferred from one mission may not transfer to another. Patches can also change balance or result behavior. A guide should not invent score values, timer cutoffs, or guaranteed medal routes when the game does not show them clearly.
How to improve your next result
Use the debrief to identify obvious mistakes such as friendly damage, failed objectives, wasted shots, or repeated corrections. On the next attempt, change one part of your process while keeping the rest familiar. Read reports carefully, choose the right shell, and confirm charge and elevation before firing. Even when the exact formula is hidden, cleaner execution gives you useful, repeatable goals.
Compare runs without inventing a formula
Record the mission, medal shown, objective outcome, friendly losses, missed shots, restarts, and any unusual damage after each attempt. Repeat the same operation and change only one behavior, such as target order or ammunition discipline. A small run log cannot reveal the hidden calculation, but it can show whether one operational change consistently improves your own result.
Keep comparisons within the same game build and mission. A balance update or a different operation can change the context enough that two medals no longer measure the same performance. Screenshots of the debrief are more useful than memory because they preserve the exact result and make later corrections possible.
