We'll use you as a distraction. You can walk up to the guards and fake a heart attack. Larry, Moe & Curly will then sneak behind the guards. I promise, it will not be an episode of Keystone Cops.
The main problem is that a paramilitary group (us) has a disadvantage vs a government agency (them). They have the people, the equipment, and the home territory. There's also the language barrier; most of the people we'd recruit wouldn't be able to blend in, which is crucial for an op like this.
There's also the question of logistics. It would be hard to transport weapons across country borders. The most likely way to do it might be to start the op in a neighboring country. But if you want to drive, you'll probably be stopped at a checkpoint. Walking isn't very appealing. I suppose you could parachute in, Fortnite-style, but that's pushing the boundaries of believability. Plus that Mig they sent to intercept the civilian plane might have a few things to say about that.
That poor guy. I wish there was something to do for him.
It's appealing to try to help this person, though. Maybe other people feel the same.
