Does the Reapers' Silent Killer skill make them undetectable when they destroy objects?
The Silent Killer ability allows a Reaper to stay indefinitely concealed as long as he/she only fires killing shots.
If a Reaper fires against a destructible target and destroys it, will the reveal chance be 0%?
Having attempted this just now, shooting at a destructible such as a radio relay, and killing it from shadow with the silent killer perk, will increase your chance to be detected as normal.
