My dad, a naval veteran, choked up a bit at that scene. You're not the only one—it's far and away the best scene of the movie.
There is also the very nice moment when a vet speaks to Cora Raikes and welcomes her on duty, not as a woman in "his navy," but as a destroyer crewmember ready to perform with a battleship.
Also watching Canales who has literally admitted that he believes himself to be half a man and has "no will to live" slowly regain his posture and decorum as a warrior and then go head to head with an advanced alien as a double amputee. Doubles as a Crowning Moment of Heartwarming and a Crowning Moment of Awesome. By far, my favorite character and plotline of the entire movie. Watching him get his medal first choked me up a bit.
This movie achieved a trifecta of heartwarming tributes: to elderly retired veterans, to disabled veterans of modern wars, and to the spirit of international cooperation. Impressive!
