Good locations for sentry guns:
For a player attacking that most important middle control point, there’s nothing more annoying than a sentry gun on a shipping crate, since it’s difficult to get shots on while being harassed by everything else.
When moving up on the enemy’s second control point, they tend not to expect you to place offensive sentry guns, but if your team is in control, they can be very effective, such as up against the wall of the building, forcing the defenders to come right out into the open to attack them.
For defending the second control point however, they shouldn’t be within line of sight of the roller door, since it’s too easy to attack from. Look for a position that covers the whole control point but has some defence, like just behind one of the pillars.
Defending the final point has a number of good positions now, but remember the point only take a couple of seconds to capture, so you’re better off preventing the enemy from reaching the point than defending the point itself. Try behind the boxes on the left, or on the tyres looking over the boxes on the right.
Another new place that should work well in defence is the new windows on the second floor of the second control point building, which provides a good view over the area around the final control point. Just watch out for attackers coming in that way.
Similarly, it’s a difficult jump but an engineer can get onto the pipe that runs along beside and just above the conveyor belt and build a sentry gun there. Unfortunately it would be a relatively easy target for an enemy in the window room, but if you can keep them out of there it’s difficult to spot.
Good locations for rocket jumping:
There are lots of little ledges you can get to in Granary. When defending the final point, there’s a low blue roof you can get on, and from there you’ll see two vent grates overhead which can both be reached, the higher one of course being cooler.
When defending your second point, you can cover the right warehouse exit from the lights just outside. Alternatively you can cover the left side from the light hanging off the wall over there.
When attacking the enemy’s second control point, you can park yourself outside their roller door on the window ledge under the pipe next to their second spawn, as seen below.
And most importantly, when defending the middle control point, there’s a set of lights over their warehouse-with-ramp exit which can be rocket jumped to.
Alternatively, following the ramp to the top leads you to a tall lamppost which can also be surmounted with a rocket jump.
