After playing through the game twice, once on recruit and UBA and finishing all challenges. I loaded up the first level you get to use the SmartGun (No Hope For Hadleys) and went down into the tunnels with the SmartGun and killed and reloaded checkpoint.

I was getting 20-30 kills every few minutes and it popped after about 20-25 minutes. Remember though this is after I did everything else to minimize the kills I would need.

Might not be the fastest but worked for me
