A few things i saw here
1. The "merc" has a helmet with 1 "goggle"
2. The "spy" that attacks the merc attacks him with a sc-20k
3. The "spy" has 6 goggles (when he get knocked down) (probably just 3 but because they wanted it to look good they made for 1 sec 6 goggles because he moves)
4. When you see the 2nd "spy" you can see in the helmet of the "merc" "reloading" or something like that.
5. It looks like the 2nd spy only has 2 goggles when he is at the left side (from our view) of the "merc" and he has a microphone
6. When the "spy" attacked the "merc", the merc hitted the head of the "spy" with his own head (kopstoot in dutch). And when the "spy" was on the ground, the "merc" probably broke his arm
That's all things i saw what you might didnt saw. I have "" at spy and merc because im not sure it is a spy or a merc
