Nonbinary Gaz cause I feel like it.
He's like me and uses He/They. Really wants people to use an even mixture of both but trying to explain that to military men is like trying to teach a slug rocket science.
Soap nearly gets there but absolutely does the "HIS PRONOUNS ARE THEY/THEM" meme without even realizing it. Price tried to research for them but accidentally ended up on Mogai pages and looked like he was going to have a stroke he was so confused. Ghost didn't get it at first until one day the two of them were sitting in the rec room and he just flat asked them to explain how it felt. Kyle explained that he never really felt like anything, like gender was completely foreign and alien. If he was forced to pick one it would be man even though it is still wrong, they like masculinity but man isn't quite right. Ghost got it the second they said that they felt like nothing and started having an existential crisis cause he didn't feel like anything either. Simon needs at least another year before he figures that one out.
Kyle never wanted to tell them that they accidentally made him feel alien and out of place cause he knew they didn't mean to. They are the only person of color, the only trans person, and as far as he was aware the only queer person all together. The guys do care but it doesn't make them feel less utterly alone, their experience is just something the guys will never be able to get as much as they try.
The breaking point is when Nikolai calls him "the team's bravest man" and he just cries. Repeating over and over "I'm not a fucking man". They knew he didn't mean anything by it but it doesn't hurt any less. It's like a cactus, a singular needle hurts but is bearable in the moment, 15 needles however is not. They lash out; insults hurled, people shoved and hit, lots of tears spilled before he storms off.
None of them realized how much they had been ignoring it, how much they had been hurting him.
After that small gifts start to show up in their room. Feminine cut shirts, makeup, nail polish, random things with the nonbinary and trans flags on them, perfumes, things that let them play with androgyny. Each of the guys went back into doing research and very consciously tried to use correct terms. Sometimes it was super small gestures like saying "my friend" instead of saying "my guy" or saying he looks pretty and sometimes it was massive ones. From publicly correcting people including superiors to making sure he had the choice on if they wanted the women's or men's dress uniforms.
Were they perfect about it? Absolutely not, but the true effort and care was what mattered.
