You wouldn’t want to. Lives could depend on the next drone’s mission, why risk losing it from a kink in the fiber? Also, the time putting it back on reels is better spent elsewhere. Fiber is very, very, very cheap compared to all other expenses in war. You don’t collect brass to re-load ammo on the battlefield either.
Another benefit is that most of the fiber will be on the ground as you get closer to the target. Your drone will get lighter as it flies.
Could you reel it back in after the drone explodes for reuse?
