Every day, our soldiers patrol the Ukrainian skies so that enemy strike drones and missiles do not destroy our cities and hit civilian infrastructure.

is one of those that effectively covers the hottest directions from where the enemy is trying to break through our air defense and strike.

Glory to the defenders of the sky!

Glory to Ukraine!

Yeah. See how very very little of that spectrum is covered by blue?

Not to mention you have twice as many green sensitive cones in your eyes.

Do you actually know fuck about shit when it comes to laser spectroscopy or are you just talking shit? I've been working in laser range finding and remote sensing for over a decade. Because if you've got a point go ahead and make it.

Blue has a shorter wavelength, and thus collides with more particles and is reflected more. That's why the sky and ocean appears blue. The human eye is also more sensitive to 450nm (blue) than 650nm (red).

I think you're confused. These aren't range finders.
