Armed For Bear

Armed For Bear is a three-star (★★★) challenge added by the Fallout: New Vegas add-on Gun Runners' Arsenal.

Challenge requirements
The Courier must kill any 15 named NCR Rangers or commissioned officers (lieutenant, captain, major, colonel, general) using a machete, ripper, chainsaw, throwing spear, or ballistic fist.

Effects
Grants 1000 XP upon completion.

Bugs
When using throwing spears for a kill, be sure to have at least two. The game checks what weapon you are holding after the kill is made. If you throw your last spear it sees your attack as having been unarmed and does not count it towards the challenge.
