14 accolades will be unlocked when the campaign is finished on the lowest two difficulties. Completing the Veteran and Super-soldier difficulties will unlock a few more awards; those are not grouped here.

Band of Brothers
Keep all marines alive during the first firefight in Semper Fi or Die. You will need to attack the alien Ceph aggressively so they fire on you rather than your four NPC allies. Human soldiers die very easily, so you need to attack aggressively to keep your allies alive. You may want to play this mission on the easiest difficulty (and with armor modules) to make the attempt as easy as possible.
Another tip — mark the four friendly soldiers (including Chino, although he never dies) once you start the mission. Those are the four marines you need to keep alive for the engagement. All the other marines can die and you will not be penalized. IGN found it handy to let the Delta squad marine at the HMG die so you can use the weapon yourself.
On the easiest setting, you can switch to armor mode and snipe/plink the Ceph who attack. Stand on the yellow container where you detached the HMG -- Chino's marines will gather there, and the vantage point you get lets you shoot all the enemies who charge your position at the trench. The condition is satisfied once you fight past the last wave of Ceph and enter the building marked by Chino.

Food for thought
Single Player: Kill a CELL operator with a giant donut in Lower Manhattan. In the mission Second Chance, you will encounter a donut shop with a giant donut. Mark the enemies in the area so you can track them. One of them will be under the donut as he walks around. Use the fasteners on the giant donut to release it -- the sign should crush the enemy.
↓
Headhunter
Single Player: Kill 4 enemies in a row with headshots. You can cloak and take your time, or armor up and wait. Remember armor mode increases your accuracy, but being seen and shot at will throw your aim off.
↓

↓
Hole in One
Single Player: Throw an alien down the sinkhole in Dark Heart. The ''sink hole'' is the hole with the water running down into its maw; it is by the final spire (before you enter the spore structure to sabotage it).
