Sometimes the way checkpoints work in the game will screw up your fultoning progress, and even reset the soldiers' stats on the field. Maybe you reset to a checkpoint and it undid your fultoning progress?
Not sure about this but I fulton alot. I also don't let MB get overcrowded.
I know if you mess up before a checkpoint you can turn game off through close application menu. I shot an S Rank soldier by accident, I threw a decoy and the game selected my assault rifle instead my sleep of riot gun, hit the ps button and closed mgs5. On load up the same guy was still there. I got him fultoned but he never showed up at mother base. Just for future reference.
Also overheard two soldiers talking about the two warring tribes in Africa and how the hatred goes back to colonism. The colony government was on the side of the minority tribe. The two soldiers said they couldn't tell the tribes apart and they all looked the same to them. They also said the languages they speak sound the same. One of them said, even the Rhodesians have a hard time telling the Bhutu and other tribe apart and if it's difficult for Rhodesians, outsiders had it even harder.
Man be careful with airstrikes. I was fucking around with bombardment and D Dog was killed. I was on a hill overlooking the ran aground ship in Africa. I put the strike on an enemy which was not close enough to hit me. I noticed for some reason the indicator was too close, I moved a bit away and D Dog didn't follow. He was still too close and I got a D Dog is deceased on the bottom left screen. Forgot to mention, he wasn't fultoned out, he was lying there in a burnt husk. :-(((((((((((!!!!!!!!!
I have no idea if he can die permanently but I didn't get a checkpoint save afterwards, so I immediately hit the ps button, closed Mgs5 and reloaded. D Dog lives on. phheewwww!
Solidus, in my current playthrough, there's no way they were all boasters.
If you are inside a stone structure with a roof, during a sandstorm the wind sounds louder standing up than if you are prone.
Not sure if mentioned but I think I see the Seven sisters constellation in the sky night sky in Afghanistan at the ruins. Yup, the big dipper is in there too.
