I personally am looking forward to using the recruit, Mark 6, or the scout.
How about you?
FOTUS. -Yoink!- unicorn warrior, who could resist?
which ever helmet is perfectly designed for combat and only the best soldiers can use that were specifically made for being absolute killing machines.
Which means all of them
GUNGNIR Pulse
Orbital with the AEON Skin whenever I get it. I think that skull looks awesome!
Recruit or MKVI
Everything else looks absolutely terrible…
Venator
All helmets here.
Recon helmet has been my favorite since Halo 3 and have always used it ever since. I will keep the tradition going. Although Venator looks deadly, as well as Wetworks. Whatever helmet makes me look like the ultimate stealth assassin. It’s my playstyle after all.
Venator with the red visor color =D

I agree. I’ll be using Recruit until I finish the Campaign on Legendary, at which point I’ll be switching between them at my leisure.
I’ll be rocking my classic EVA helmet… yeah sure people seem to think it makes head shots more easy but I’m a driver… and I like the extra large visor to see better… the EVA helmet was meant for vehicle piloting after all… yeah I know it’s only canon but that’s my point

I think of Pinhead Patrick when I see the FOTUS helmet.
But in response to your question, I’d say I’ll go with the Recruit w/ Prime skin, Venator w/ Raptor skin, Recon, and Dead Eye.
Air assult, scout and soldier looks attractive to me o.o
Recruit with the Prime skin.
Either the Recruit (with prime skin), Aviator, Scout, Warrior or Mark 6. I need to see them all on my tv before I make up my mind
FOTUS
Mark 6.
The wetworks helmet. Love assassinations

Huh, nah man I don’t see it.
OT, imma be rocking my Deadeye.
FOTUS
I think that the helmet part of it is one of the best in the game, but then people focus on the horn and go into hulk mode.
