My personal headcanon is that Wendigo's tend to be hoarders, although that particular instinct has been heavily repressed by Ghost due to a mixture of intense military training and sheer willpower. However, even though Ghost won’t randomly collect things that catch his eye in the field or on base, he still allows himself to covet essential items such as his tactical skull mask, his numerous skull-themed balaclava, and his favorite mug.
Seeing as they are particularly territorial of the things (or people) that they consider theirs, it’s kind of a big deal when they start giving and/or sharing stuff with others because it’s a sign of kinship and/or affection. So Ghost will randomly offer to make his team members a cup of tea when he’s making some for himself, subtly sharing with them. But he only does little things that wouldn’t be recognized as the affectionate gestures that they were unless you know him well.
So, for example, after the “Alone” mission in canon Ghost would simply let Soap keep the knife that he had found in the unfortunate Shadow that had crossed the Ghost’s path. To do this, Ghost probably just wouldn’t bring up the knife at all once everything has settled down, which in itself is a subtle indication that Soap has permission to keep it because if he didn’t want Soap to have it then he would bluntly ask for it to be returned.
Unfortunately, Soap still recalled how Ghost had said that he would like the knife back during the whole mess that was “Alone” and would totally approach Ghost privately to try and return it to him. Though Ghost wouldn’t move to take it, merely leveling poor Soap with that empty stare of his until Soap lost his nerve and beat a hasty retreat. The bizarre and nerve-racking experience would lead Soap to never try and give that particular item back again, but he does start carrying the knife with him on missions.
Due to the typically uncontrollable/untamable nature of his particular species, Ghost’s instincts are the hardest to repress, which makes hostile and bloodthirsty his default state of being. But with people that he sees as his (the 141, essentially) the urge to eat them decreases a significant amount, but that only makes the instinct to possess them all the worse. It’s a trade-off that Ghost is more than willing to make though, because he likes his team alive.
One of the pros of being seen as one of Ghost’s “possessions” is, first and foremost, that if he were to go into a feeding frenzy then you wouldn’t be on the menu. There’s also the simple fact that he’s easier to direct toward a target (or targets) while his higher brain function is switched off in favor of mindless feeding, which usually only happens when he’s “fatally” wounded in the field.
Not that he can actually be severely injured or killed by anything other than fire, that is. So Ghost is able to heal from wounds that would be a death sentence to a human and even other supernatural creatures because he only actually has one thing that can do serious damage to his person and since the fact that he’s a Wendigo is kept under lock and key -along with the knowledge that the supernatural exist in general- that means that most people wouldn't think to bring a flamethrower to a gunfight.
Ghost’s mind is dark and more than a bit twisted due to being a Wendigo for longer than he had been a human, so I see him as having a bit of what I like to call “Hannibal Mentality” where he just kinda wants to possess people and keep them with him forever. His way of doing so? Eating them.
Not, like, while they're alive mind you. But say, Roach were to die on a mission with Ghost, who would be compelled to eat Roach’s body since he doesn't have bodily functions that cause him to produce waste, so whatever he eats is quite literally with him forever. It would be challenging enough for him to simply give Price the dog tags instead of keeping them for himself, but there would certainly be no body to give to relatives or next of kin.
