So I'm crouching on the road leading past Fort Bannister, trying to snipe the launcher-wielding Talon Company guard. I'm zoomed in with my sniper rifle when I hear a growl to my right. I stop, turn and look an there's a Talon Company guard dog headed my way. I switch to a hunting rifle and prepare to defend myself. Except he runs right past me - literally within knife-strike range - and keeps going. I had no stealth boy active and that character's too low level to get the Animal Friend perk. So I turn and aim to the left, and sneak attack critical him from behind, killing him in one shot.
Oh and earlier, I'm near Vault 101 creeping up on the overpass outpost - a raider camp. I get the attention of one of the raiders and she comes running, I position myself so the has to run into my line of fire before she can turn and start attacking me. When she shows up, I enter VATS and shoot at her head with the 10mm pistol Amata gave me. Two shots, and the raider goes FLYING off the cliff. I Never did find where she landed, but she flew far 'cause she was a good six feet or more from the cliff. That cliff is terraced, so she may have fallen on one of the levels before the base of the cliff, or all the way to the base.
