*Points both thumbs at self* This guy.

True story, I killed it with the War Club. I took a hit but once a Super Slam connected it was down and it stayed down.

Fallout 3 Jiangwei's Shocksword and Chinese Stealth Armor

Patrolling the Mojave/Chillin' on the Strip-Daniel's outfit, Daniel's hat, Authority shades.
Serious battle- Enclave Remnant Power Armor.
Holorifle+ fully modded
Machete gladius
Plasma pistol GRA +++
Oh, Baby!

Graham's armor and Boone's beret + rebreaher

Survivalist's rifle
.45 auto or Sleepytime
Riot shotgun or Pushy
Annabelle
Thump Thump
C4 and frag mines as detonators

the .45 auto has a rate of fire and accuracy (once upgraded, but also esp. with the SWC ammo) such that I tear all before me a new one

Right now I've got Riot Gear on.
With the GRA Anti-Materiel Rifle modded with the Carbon Fiber parts. Plan on also getting the custom bolt. Who would want to suppress this baby?
I've also got my Trusty Ranger Sequoia at all times.
And Blood Nap for those silent kills.

Of course, I only use hand loaded rounds haha.

I see I'm not the only one who's reminded of WWI British troops when looking at NCR soldiers.

As for my favorite gear:

My deathclaw killer: Holorifle fully modded
Long Rang: Anti-Materiel Rifle (GRA)

Spacesuit and helmet for radioactive areas
Rebreather for under water
Sneak Attack Sorry don't know that word

Armor: First Recon Beret, Lucky Shades, Spacesuit

My favorite weapon in FO:NV is the Mysterious Magnum, hands down and no questions asked. That and the .44 Magnum with the heavy frame mod.

And I'm fond of the Merc Adventurer and Merc Cruiser outfits, as well as the raider badlands.

Favorite armor for me is a tossup between the basic Riot Armor and Elite Riot Armor. I love all the extra pouches and bandoleer of ammo on the Elite version and it's helmet, but I prefer the basic armor's lack of shoulder plates.

For weapons, it's the Marksman Carbine and .45 auto, all the way. Energy weapons are a engaging gimmick for me, and I'd never been a heavy weapons fan. Same goes for melee. Though if I must choose a melee weapon, I'd go for FO3's Trench Knife.

For armour; Remnants Power Armour, Desert Ranger Combat Armour
For weapons; Guass Rifle, (GRA) Tri-beam laser rfile

GRA Tri Beam Laser Rifle+++. I love that thing!

As for armour, I dunno, I'm kinda obsessed with the ones I found in LR, as LR is the most recent DLC, I kinda got bored of the other attire (being a style over substance guy) I really like to look at the stuff ya know!

But I really like Marked Beast Eyes Helmet, Marked Scout Armour and Marked Patrol Armour.

For normal work, I use Elite Riot Gear, 1st Recon Beret, and the Authority Glasses. For normal weapons, the Gobi Campaign or the fully modded Hunting Rifle (hopefully Paciencia soon), with handloaded .308 JSP, Sleepytyme with 10mm JHP rounds, and Rawr's Fist, cause unarmed is manlier than melee. Even with the awesome bowie knife.

For stealth, the Reinforced Sierra Madre armor, the aforementioned beret and sunglasses, and the fully modded sniper rifle with .308 JSP (picking up the COS soon), and the same two secondary weapons.

For my crazy bullrush, like killing Caesar (the [censored]), Elite Riot Gear + Helmet, and 1st Recon Beret, and the Fist of Rawr, along with Mercy, the CZ57, and the Dinner Bell, with whatever random rounds I can get my hands on. With GRA, it gets kind of crazy.
