Unsuccessful landing

A military helicopter has been shot down over Army Warehouses; a case with military documents landed on one of the power towers. Kuznetsov wants you to get this case back.
== Walkthrough ==
The case itself can be found on one of the power towers, chosen randomly.
Try kicking the case off the tower by shooting it, preferably sideways. Keep in mind that it breaks when damaged too much, softlocking the mission.
== Notes ==
* Don't bother using a smallbore rifle since it'll barely move the case at all--birdshot aimed at a corner will immediately knock it off of the tower.
== Bugs ==
* Rarely, Kuznetsov doesn't have the dialogue to accept the case.
