Tac insert+ any of the above weapons or lmgs will surely make whoever is in the jug suit rage.(Assuming it's a assault one) Because jug is a killstreak.......I never felt so much anger playing this game before.
LMG's can absolutely murder juggs from far away...I also like the PM-9 ext mags+ rapid fire...you can dump a clip into them before they turn. Obviously akimbo FMG's dump ammo well but they're nooby. Explosive are good, like the RPG.
Juggs make it PRACTICAL to get the dictator achievement, not EASY. I'm not sure how many bullets it takes to kill a jugg, but it's enough that you'd need 3-4 juggs or very tactful waiting to put a whole clip into him without missing.
