Oh my god. Now, before this one, I thought the Engineer challenge to hit painted targets was the most annoying. That challenge, which still isn't tracking progress I might add, is not as annoying as the Supply Pouch challenge.
So, for those that don't know, the challenge is thus: 135 resupplies with the Supply Pouch. Here's the fun bit: It doesn't count if the person doesn't NEED the resupply. Which does make sense, however, you have no idea of knowing whether or not someone actually needs it, so you just have to throw it at someone and hope you get the points for it. Usually you can make an educated guess that someone needs ammo or is hurt, however, you will be tempted if successful to throw more. Here is where you end up supplying someone who didn't need it and thus waste a charge.
You only spawn with 3. You can only ever have a maximum of 3. And they resupply VERY slowly. I'm pretty sure you get Grenades faster and those take forever.
Which means you'll need to go away from your teammates to set down your Supply Bag (as you don't want to risk them getting health and/or ammo from something other than your Supply Pouches) and then you wait........ and you keep waiting.......
And you just rinse and repeat that. About 180 times, because by my rough estimation, about 1 out of every 3 Pouches I threw I either missed (rare, but it happens and they just disappear into the ether, you can't pick them back up) or they weren't needed (they disappear into the ether).
Is this challenge difficult? No. But it will take a very long time. It's just busy work. Busy work that isn't particularly helpful for you or your team because the Supple Pouch sucks. A lot. But you have to do this... just to unlock a different gadget that also sucks. A lot. Huzzah.

That'd the goliath supply pouch right, the gadget you have to equip?
I did it a while ago now, but I found that the main support special supply (x) worked. So just dropping them near objectives, or behind a group of players was much faster.

♥♥♥♥♥♥♥♥. The challenge says it needs to be the Supply Pouch. I'll be so pissed if I could have just dropped the bag this whole time....

"The challenge says..." Yeah but it's EA.
Like I said, I did it a while ago now, and I don't know if it still counts the regular supply pouch, but it used to work that way so it's probably worth checking if it still works.

♥♥♥♥ my life.

the moment a bullet leaves their gun, you can resupply them.

Why the hell wouldn't you be dropping that anyway?

I just sat in casual breakthrough camped a spot enemies are unlikely to get to, drop my resupply bag and just toss the pouches into a crowd of friendlies defending the cap. It took me like three matches to do.
The pouches home in on those who need supplies and if they don't they sit on the ground to be picked up as soon as they're needed.
Honestly, most of these large amount achievements are doable on Casual Breakthrough, like the 300 Recon spots on an obj. Just put a drone up as an attacker and get free spots. as all the AI sit in the cap.

The pouch auto targets players near you as you throw it. I just completed this in a couple of regular breakthrough matches with less than 20 to finish in the first match.
Second mach it was less than 2 minutes and done.
For anyone in the future who reads this just follow the largest group of teammates and throw your main supply bag down and start tossing them around when everyone starts shooting.
Super easy to get it finished.

This is easy compared to the suppression challenge lol.

Yep you could have done it with the supply crate lol. I got mine done in about 2 games by using both the crate and pouch. You can really throw those pouches far, like a mini grenade. I've definitely saved a few allies from death with clutch heals this way.

This is easy compared to the suppression challenge lol.
Suppression one requires you to play like an idiot because it's so, so much suppression. To the point where you're trying to miss while doing things like Casual Breakthrough to stack it up.

For anyone playing season 4, you can no longer use the resupply bag for this MAAAAAAAAAAN it sucks
