Several White House officials revealed to NBC News that President Donald Trump is growing increasingly “worried” over Canada regarding its ability to defend its borders, with one official saying that Trump’s concern stems from his “vision of ‘solidifying’ the Western Hemisphere,” the outlet reported Sunday.
If you look at Ukraine, yes guns are involved, but they’re arguably succeeding in their defense principally with the use of kamikaze FPV drones strapped with big bombs. They’re able to chase down individual soldiers hiding in buildings, trenches, and even drainage pipes. They can also take out vehicles.
You’d want to mass produce these drones. Additionally, since the radio signals can be jammed, develop the fiber optic drones too.
I would prefer development of anti drone technologies using small current electric fields instead of clogging up Air space on the battlefield. Also bird shot is great for taking down drones.
