Motor Pool is the third chapter of the fourth act in Gears of War: Judgment.
After entering a small storage area you'll find the Declassified Mission at the nearby wall.
"Kilo Squad made use of Locust shields, disobeying direct orders to avoid enemy equipment."
Activating the mission will leave you with only a Lancer and a Boomshield which won't be much of a challenge if you're an experienced player but it will give you less mobility and unable to use any weapon other than the Lancer. Cole remarks that they didn't really violate any orders since the Boomshields aren't technically weapons.
Go straight until you find the exit, once you open the door you will find a Locust outpost full of Drones and/or Theron Guards and Tickers with several turrets around the vicinity, try to use the Tickers to you advantage as they will make a lot of damage to your enemies, some Boomer classes might join the fight, choose the better strategy to deal with each class. You can also walk into a small room, destroying the fences inside, to try to ambush the Locust from behind.
When you have past through all enemies and reached the turret take out the gunner (if there's one) and move towards the burning storage area and finish off the Locust inside. Once all enemies are out head to the door at the end of the room and you will continue towards the next chapter.
There's a COG Tag behind what appears to be a small conveyor belt with some warning sights over it.
