Completed the mission without using the fire extinguisher in Fire From The Sky

It is recommended you play this Co-Op mission, Fire From The Sky, on easy. This is one of the more simple trophies/achievements as all it requires is that you do not take an excessive amount of damage at one time. To minimize damage you should always focus on enemy armor when they appear on the map as those are things that will cause severe damage to your helicopter. Communication is key between the gunner and pilot. Make sure the pilot knows how to fly the helicopter and use the rockets effectively and as the gunner be aware that you have a laser guided missile to aid in taking out enemy armor. If you do get damaged just don't use the fire extinguisher
