Exactly, so like I pointed out earlier, certain logical details are left out to make it more cinematic; e.g. we get to see the faces of our heroes while the villains remain faceless drones, and there’s just enough tech stuff thrown into the frame to make it look convincing enough so as to allow for a suspension of disbelief.
PS, I’m assuming this is the prototype you were referring to;

(It certainly looks more realistic, but it would have made the final trench-run scene a lot less interesting and emotionally engaging.)
