So I've seen officer-looking guys running around the battlefield with p90s and the like, and I can tell they are different because of the beret gold vests and pants and the like, so I'd like to ask if it is possible to look like one of them upon reaching a certain rank? I looked around and didn't see any answers, and any here would be much appreciated. Thanks!

I do not think it's possible, they look pretty cool - yes. They have very neat AI as well, they call in reinforcements and artillery barrages regularily, and lead other AI into battle. Players with a high rank can sometimes recruit them into their own squads as well.

All three factions have these guys, just they look different.

Oh! They also have a "Type III Vest" which is a little more effective than the standard "Type II" that we, as players use. You can obtain their vests by melee killing them.

Hope this helped!

It would be cool if you could choose to change your outfit as an officer. The higher the rank, the more options you have or something.

A scale something like this:

2Lt to 1Lt (same options)

Cpt

Major

Lt. COL to COL (same options)

BMLG Gen (same options)

General of the Army (MC Hammer Outfit)

Only half joking on the last suggestion

I've made it possible in the "Running with Trench Foot" mod to buy an Officer's Uniform at 20,000xp, though my Officers are different from the default game.
