Ranger Takedown

 is an unarmed perk in Fallout: New Vegas.

It's acquired by being successful in a speech challenge from Ranger Andy after he tells you about his multiple leg injuries. It can also be acquired by completing an unmarked quest which requires you to check on Ranger Station Charlie and tell him what happened there.

Bugs

 * When you learn the attack after you learn it when you talk to Ranger Andy it will come up again that you learned the Ranger Takedown and it will freeze.
 * Prior to patch 1.2.0.31x, learning the Ranger Takedown without Raul Tejada will break the Old School Ghoul quest. This can also be fixed with Console commands in the PC version.
 * If you use this skill on a friendly member of your team and manage to knock them into a state of "Unconscious" while they are still knocked down, their body will fly into the air shortly afterwards, to the height of an average sized building, and when they hit the ground they will get up like normal.
 * The attack may stop working altogether at random moments. This may be fixed by restarting the console.


 * When using this on dead characters repeatedly, it can complete the challenge Knocked Up.
