Grenades do not seem to work

EMP bullets for .50 caliber rifle.

any Armor Piercing sniper rifle bullet does the trick.

if you get your hands on an explosive bullet, even better, but I found carrying them for rare occasions of use just isn't worth it. AP works better as a secondary bullet more useful in more situations.

you can simply hack 'em with your drone, take them on their back, and simply use the hack command... for the last mission, .50 cal can help, or multiple shots with other weapon will do the trick...
you can also hack the mines with your drone, it's the same process to hack turrets...
