Grant is a long time NCRranger, best described as the "shoot first, never ask questions" type of soldier, someone who doesn't mind going into combat, so long as his soldiers shoot alongside him. He was injured at one point during his service. He also seems to enjoy (and even volunteer for) more dangerous missions.
Wild Card: Finishing Touches: As an optional objective, make sure Kimball doesn't die while giving his speech; Ranger Grant will act as the point of contact.
Despite wearing his eyepatch on his right eye, he takes aim using that eye. This is due to the aiming animation only being for right eye dominant characters.
During the quest You'll Know It When It Happens, contacting Grant via radio will include the option "We're all fine here now thank you, how about you?" This is a reference to a scene from Star Wars Episode IV: A New Hope, when Han Solo answers a call in the same manner for the now-dead detention level guards while in the process of rescuing Princess Leia from the Death Star.
At some point during development, Grant was instead an NCR captain by the name of Graham. References to this name still exist, including in his GECK Editor ID: VHDCaptainGraham.

PCPlaystation 3Xbox 360 If Ranger Grant is told in person about the Legion sniper on the tower during the quest You'll Know When it Happens, or if the "goodbye" conversation option is chosen before the quest, he will still sound as if he is talking through a radio even though the conversation is occurring in person.[verified]
PC Sometimes he says that they're preparing to protect the president, and the only dialogue option is "Goodbye." To fix this, reset Ranger Grant by typing prid 0013721F then disable and last enable.[verified]
PC When you say "I have to go" he will say bye in a different voice.[verified]
