An Ear to the Ground

An Ear to the Ground or Team Spirit (GECK name) is an unmarked quest in Fallout: New Vegas.

Detailed walkthrough
Simply kill any Legion soldiers and bring back the Legion ears to turn in.

The objective is to kill as many Legion soldiers as possible. The best way to do this is to activate the quest, and then do Restoring Hope. You need to turn in at least 30 ears for Private Sexton to give you a reward of 100 caps and 6 beers. After the reward has been given, you can no longer collect Legion ears.

Rewards

 * NCR fame.
 * There is bonus applied to the third part of Restoring Hope. Every 10 ears turned in adds a morale bonus of 1 for a maximum of three. This bonus is applied to the Nelson attacking forces.
 * After you have turned in enough ears, you will also receive a number of beers and 100 caps.
