1. Grab a MX 3GL 6.5 mm rifle and a few 40mm 3Rnd HE grenades.
2. Fire the grenades but notice how the rifle bolt animates as well as if you had just fired a shot.
3. Reload the GL, look at the side of the weapon and notice how the magazine of the rifle comes out and then goes back in, as if the weapon is going through its reload animation as well.
