Finally got a run that I'm happy with. Thanks to a video from Haru Minamo, who took inspiration from Usetsu "雨雪" and Wakiyaku "脇役", I was able to improvise this route.

The strat is as follows:

• at the start of the mission, call Pequod to the LZ close to the Easter Communications Post.
• once you move pass outpost 24, Pequod should be attacked by the truck driver.
• Pequod will engage the truck driver and kill him, hopefully damaging the truck a little bit.
• once that happens, call Pequod to the LZ at the Easter Communications Post.
• get in the truck and drive it to the Easter Communications Post, occasionally hold the stance button to avoid being detected.
• once your at the post make sure to drive towards the guard at 02:10 so he doesn't spot Snake, and for his buddy that stays near the Comms Equipment to move to a different spot.
• park the truck at the same spot I did and hop on the truck bed, then start kicking the truck.
• keep kicking the truck until it gets destroyed and fulton yourself out once the truck explodes.
• the explosion should destroy the Comms Equipment - you can tell it worked if Miller congratulates Snake before leaving the mission.

Time is based of IGT.
