Fair point, but it's not an apples to apples comparison. Being a peon for the US army/marines is one thing, being cannon fodder in the Ukrainian army is another one.
The US army treats, equips and protects its soldiers way better than any other army in the world, so US soldiers are a lot more likely to be cooperative with orders and conscription process than armies where you're just given an AK and shipped to the meat grinder.
For context, even the German military had a shortage of underwear and dog tags for its conscripts due to underfunding. Now imagine what the armies of Ukraine and Russia are like.
I did signals intelligence in the USMC a decade or two ago.
To paraphrase a discussion I heard: "you do this job or we ship your ass back to the infantry tomorrow and strip your clearance. don't fuck up."
that's how. the option is to learn to do X and Y, or learn to dodge drones.
