5-8 Bleed Stacks on Critical Hit.
1-4 Bleed Stacks on non-Weak Spot Hits.
5-8% Strength for every shot fired during continuous fire. Stacks 5 times.
Critical hit chance scales by your current heat level up to 27.5-50%. Also increases critical ranged attacks damage by 4-10%.
With the recent buffs to common enemy shooters (Patch 1.4 Secrets of the Machine God), Smoke Grenades are more valuable than ever to defend your team, not only to prevent your team from getting their toughness shredded, but also to mess with enemies' AI and buy your team valuable time.
This build is specialized for responding to crisis. Sacrifices individual lethality for better clutch potential at any given moment. Do NOT chase after making your Scoreboard mod look good.
Situations where using Smoke Grenade is a good idea:
Remember to not only use Infiltrate to revive. Low Profile allows you to focus on Elite and Special enemies while the rest of your team takes aggro. Your teammates having YOU on their team is a huge gamble and this is where you really need to make sure your existence pays off. When you Overwatch, use a spare charge of Infiltrate offensively whenever you can. If you're really hesitant in doing so, just hold on to a Concentration Stimm.

I should've really made this guide when I haven't been awake for more than 24hours. I don't feel like redoing this so I'm just gonna post it now and add more to it later if I remember anything else.
