If you shot a gun indoors you wouldn’t do it again unless you had to. And special operations types often train at indoor ranges and such. They also probably wouldn’t celebrate the murder of a bunch of civilians.
Blocking the villain with one hand easily. Being seen by strangers doing superhuman things. Them thinking of him as devilishly handsome. Showing powerful aura. Some girl with indifferent look and cold aura along with beautiful face and jade like skin. God, it's only been 5 chapter and you're already filling this novel with trash level cliche events.
Don’t forget to add in that the American special forces are cannibals! Some enemy forces (maybe some Americans too) in the previous wars started fantastical and gruesome rumours for the purpose of fear and propaganda.... they kinda blew out of proportion when terrified soldiers heard them. Cannibalism was just one example....
