This is another easy achievement. For this one you will only need to complete the level Carrier and all its objectives. I will only cover the bonus objectives as you cannot miss the main objectives..
Objective 1: Defuse 3 bomb charges
Objective 2: Rescue 3 hostages
-When you enter the ship and go up your first flight of stairs you will hear them talking about arming charges, the first one to defuse will be in that room
-A little further on you will be heading down a ladder and just before you go down the second ladder you will hear voices in the room to your left left, breach that room for your first hostage
-After that go down the ladder and run down to the end of the corridor and there will be your second hostage to rescue at thd Door straight in front of you
-In the room next to where you saved that 2nd hostage will be the second bomb to defuse. The room has missiles passing through and if you went in that room straight from the ladder it will be in the right side of that room
-In the next room where you have to use your smartphone to hack two computer terminals will be the last bomb to defuse, Its by the one in the middle part of the room with the red lights and next to a computer you need to hack
-Then just as you leave this room to move to the next is the last hostage on your right hand side.
Then when you finish the level you will be 15g better off
