Action scenes of this movie were executed really well...especially the one where Chris rescued the kid from kidnapers and took out 10-12 people using Ak's and anything he could find in the surroundings.
Extraction director Sam Hargrave, being a stunt man himself designed the action sequence of this film flawlessly.
Little things were quite noticeable like Chris practising good muzzle discipline when in public, smooth reloads and using the right gun for the right situation( especially Glock 17 in close combat and Ak's/M4's in Mid range).
