Now that you have everything needed to start, Go to your missions tab and start up the mission, (THE WHITE MAMBA) Once You drop into the mission area, head your way over to this outpost.

Now That you have arrived to the outpost, Take out the child soldiers QUIETLY, it is best you do not get spotted or cause the alarm to go off. Fulton extract every child solider in the outpost, For clearing the outpost you get 300+ Heroism, and for every child solider you fulton you get 60-120+ Heroism.
(There is also a Rough Large diamond in one of the Tents so make sure to grab that so you can get some extra gmp)

For the last Outpost head over to the main mission objective, Do the same thing as the last outpost and Fulton extract every child solider. Remember to do all of this without making the alarm go off or get caught.

Go up to the mission objective and try to sneak up on Eli (White mamba) so you dont have to fight him. (if you were not able to sneak up on him, You can use CQC to fight him or you can use the riot stun smg to beat him.

Now that you have finished the mission, You will earn about 3000+ Heroism, This Guide takes around 5-10 mins to complete, You will also lose demon points for every child you extract. -120 Demon points for Fulton extracting a child soldier. You do also lose more demon points if you extract the child soldiers via helicopter (-240 Demon Points) but it is faster to Fulton. You can repeat this guide as many times as you would like there is no limit. If you would like to see the guide in video format, watch the youtube video I provided. Thank you for taking the time to read my guide and I hope this can help you out!
