Combat engineers have always had one of the most dangerous roles on the battlefield. Breaching obstacles under fire, clearing lanes, and pushing forward through fortified positions has traditionally relied on ground deployed smoke, timing, and luck.In this video, I break down how drones are now being used to deploy airborne smoke screens to protect combat engineers during breaching operations. Unlike artillery or vehicle launched smoke, drone delivered smoke can be moved, repositioned, and shaped in real time, adapting to wind conditions and changing threat angles.Drawing on my experience with smoke in artillery, I explain where traditional smoke works, where it fails, and why drone based smoke screening changes the equation. We also address the reality of thermal imaging, counter surveillance, and how smoke still plays a role in modern warfare when used correctly.This is not speculation. This is how breaching doctrine is already evolving.
