I'll have my MC jump into action after Skye's promised briefing-on-the-way narrated

I'm planning on having my MC wiping out the AAA operators in long distance, then bugging their radio communication channel and use a Natural Language Processing software to automatically predict the enemy's order of battle in their current operation.

How far should I narrate my MCs success rate?

Oh, one more thing, is this current mission supposed to be "easy" for the Raven or I can have my MC getting into trouble?
