So I been thinking on this more and after the conversation last night, Raz gave me insight into how this might shape up. In the context of Star Army, trauma in my mind is different from how we may see it. These are super soldiers, captain America if you would, who are designed to be very good at what they do. So shout out to Raz on his thoughts on trauma.
This role could be one that fills the need to help overcome logical (or illogical) emotional thoughts. Here is one example of an event. Say soldier is second in a column of troops. They have concluded the enemies who just entered the hallway are an immediate danger and must be killed ASAP in order to save the group. There is just one problem, the weapon they have will kill the soldier in front of them in the process. If they perform the action, soldier is dead (though they can respawn) and the team is saved. If they don't act 3 are killed, instead of just one. Which I'd contend the super solider ran the numbers and has this information. The one saving grace is that the solider who knew, died and when STed no longer remembers. However, since everything is being recorded there is a chance they can learn of the truth. Clearly a no win situation. Though in the context of performance, if they acted then they performed their role to the highest possible standard. Might even get a medal for this. However they just blasted their buddy to dust. If they don't act, they they failed to perform at perk performance.
I also see areas with conflict between the designer super soldiers and others who are not gifted as such. Just think if you was the 5th person in that column and just seen your friend blast another friend into space dust. Feel one might really consider who your friend and foe is.
This MOS I see opening a new path for emotional writing, to give a chance to have a conversation to explore this dynamic. This to me would be different from a caretaker and counselor is as follows. Based on MOS, caretaker has skills related to upkeep. It does include listening but I'd content they do not have the training to dive into a topic of this depth. Regarding counselors, this I see running closely along side this MOS. The main difference being that chaplain has focus on healing and processing, compared to a counselor who work towards an action plan to help said person overcome. Personally I'd content if there is too much conflict, a counselor would recommend them being ejected from Star Army. As they would be a clear threat to the mission if they are not able to follow their programming. Were as a chaplain is not shackled by the mission and puts focus purely on what the person needs.
I am working on having a turned NMX go down the route of being an emotional support. However I want to RP this out prior to making anything on the wiki. Feel this will give me a better context to work with to design a clear wiki page. This has parallels with other MOS so it might just be concluded they get the badge of say counselor. I'd be looking at this while making the RP.
Just my thoughts and hope this adds to the conversation.
