How to get NCR Ranger armor/gear in Fallout New Vegas?

As seen on the wiki, there are a few ways to get NCR armor:

1. With a "liked" or higher reputation with the NCR, Colonel James Hsu will give the Courier a key to the NCR Ranger Safehouse. Inside are a set of NCR salvaged power armor, NCR Ranger patrol armor, and the NCR Ranger combat armor. There is also a reloading bench and some empty foot lockers, alongside a hunting revolver, assault carbine, and trail carbine. Note that all armors are in poor condition.
2. This armor can be found on NCR Veteran Rangers throughout the game in areas occupied by the NCR (e.g. Camp Golf, the NCR Ranger Safehouse, Ranger Station Bravo, Camp Forlorn Hope, etc.) or if the Courier is labeled a terrorist by the NCR, as there will be ranger kill-squads sent to eliminate them.
3. There are several dead NCR troopers wearing this armor at the Long 15 if you choose to nuke the NCR upon completion of The Apocalypse. (Lonesome Road)

Although I'm assuming #3 doesn't apply to you so much.
