For gaming I would say it needs to go at least 10k+, and even for that, you need to have a primary/match gun with an optic you are gentle with, a training/dry fire gun that can see more abuse, and a backup training/match gun for when one of your others goes down. Maybe it's just me, but I don't like paying close to $1000 in match fees, ammo, gas, and lodging to have my optic die on me and ruin the whole match, so reliability is extremely important.
For LEO/Mil, unless you have vision issues that preclude you from using iron sights, I don't think any current optics are anywhere near reliable enough for use. For a LEO/mil with vision issues I'd still recommend a three gun system like above at the minimum, with the gun you carry every day seeing very low round count and usage.
