He actiivates his tageting systems, appears to be fully threatening to unleash a devestating orbital bombardment...

Also, intersting technology note: Railgun turrets are evidently aimed by low-intensity lasers, which, although powerful enough to penetrate hundreds of kilometers of atmophere and still generate an appreciable return, also interact enough with a planetary atmosphere at ground level to generate a glow visible to the human eye and (presumably) still not cause appreciable thermal heating to solid ssufaces.
