Bingo, the most simplest way to get it. Sentry guns, remote sentries, pavelows, attack helicopters. you may die to the enemy but while going for that challenge eh, who cares at that point.

Have you tried using it in an Overkill class and have it on your back?

They sure do cuss us riot shielders alot bet most of them were probably snipers.

Since undertaking this challenge I've found a few ways to help speed things along. Below are 3 setups I'd recommend using depending on how you want to play the game. All setups are for dropzone and all killstreaks are set to assault with sentry gun, attack helicopter and pave low (not sure if this matters so much in dropzone but I like to think it increases my odds of these showing up in a game).

#1 : Riot shield with melee + a pistol + throwing knife + smoke grenade, sleight of hand + blast shield + steady aim (This setup allows you to gain control of the dropzone)

#2 Riot shield with melee + pistol + throwing knife + smoke grenade, scavenger + blast shield + sitrep (This setup allows you to gain control of the dropzone + detect enemy traps + If your good with knives humiliate the enemy)

#3 Riot shield with speed + a silenced pistol + throwing knife + smoke grenade, sleight of hand + assassin + steady aim (This setup allows you to concentrate on deflecting bullets from killstreaks while remaining under the radar)

P.S. 47545 bullets deflected sofar ( only took 2 months & I'll be finished in 2 days max )

Seriously....I'm about to hit prestige 18; there's no reason that any of these title counts can't be made to roll over when you prestige, such as the weapon kill counts do. First time I started working on some of the support titles I got a rude awakening when I prestiged with 135 recon drones called in... I figured sweet, I'll prestige and pick up the next 15 then have my title and move on to something else. But sadly, it started from 0 all over....calling in 150 recon drones isn't fun.... neither is trying to pick up 50k bullet hits on your shield when if you're lucky you might pick up 200 hits a game. Please fix this devs.
