Actually the trick I found with that mission was that I typically did more damage to Mobius than the enemy did. So, instead of rushing along I'd allow him to run ahead and get hit a bit while I picked out my shots. By the end of the mission Mobius would be down to about 50\% health.Additionally, when you make it out of the compound you can trick the NOD Officers into coming after you rather than running into them by picking them off before you round the corner.
Also, I found the laser rifle in combination with headshots worked best for quick take downs.
