R2- Place support juggernaut
L2- carepackages they will be support streaks though
L1- place smoke bomb
R1- label enemies on the map for your teammates
I would recommend using the these streaks for best results
Juggernaut support- the one with the riot shield that provides you support
Juggernaut Suit- the one that makes you a juggernaut
Odin- another juggernaut
what you should do first is get all of them then run your odin and make sure the juggernaut you drop does not die once your done the Odin get your juggernaut suit and then activate the riot shield support..........
You now have three juggernauts on the field
There's a wait period for each of the four. Smoke/Radar support are a very short wait period (just a few seconds), while the carepackages are a longer wait period. I believe you can drop up to 3 carepackages, possibly 4 at the most. You only can place 1 juggernaut though.
If you're going to be running support streaks, and you usually get the amount of kills for the Odin early-ish in the game, PainofJustice's strategy is best. I've done it quite a few times, and it really screws up the other time. Even if the other juggernauts don't do much (kills-wise), they still distract and delay the opposing team from doing objectives and it also takes the attention off you for some easy kills.
