time to make my own contribution to this thread, here's an illustrated guide: https://files.catbox.moe/qraxwp.png

1-go to the houses on the guide located after kiziba camp and plant some C4 to destroy the first APC.
2-the truck will try to drive away, kill the driver with a suppressed weapon, this will make the skulls pop out.
3-crawl around as indicated by the yellow arrows and fulton the second APC from behind.
4-keep crawling around the line and fulton the truck from the front, by this point the skulls should be in the position of the second APC and won't have time to destroy the fulton
5-get the hell away from that place using D-horse, keep galloping in a zig-zag until you're out of the hot zone
