It wouldn’t be a terrible deployment to go on. You are state side, and you won’t be killing civilians or aiding terrible dictators. Probably just marking targets and building out fencing. No worse than training. The only thing that would really suck is that rules of engagement would most likely not allow you to shoot back at any cartels that might be shooting at you, but that’s not new there are a lot of shitholes in Africa where that happens. Doubt you would have anything to do with actual migrants at worst you might have to escort an agent in to do the arrests and paperwork
The units assigned to the border are sustainment/logistics, engineers (construction), and military police replicating the 2010 National Guard deployment of ~2000 or so. They are not shooting at anybody.
I’m having a hard time connecting UN peacekeeping missions with American border patrol, how did you get here ? The only thing that would really suck is that rules of engagement would most likely not allow you to shoot back at any cartels that might be shooting at you, but that’s not new there are a lot of shitholes in Africa where that happens.
There are a lot of missions where US troops are training up local militias and friendly forces. We’re not really officially deployed there so if someone gets shot and shoots back it creates an incident. I’ve heard some stories from people ive casually had beers with of those going bad and not being able to shoot back at the hostile. The border patrol mission would likely be too political to allow for an incident to occur.
