Metal Gear PMCs Logos.
Following logos/emblems included. Note that some have changed throughout the series. Here's the list and what era/game are from. 

Desperado Enforcement LLC. Metal Gear Rising: Revengeance
Diamond Dogs. Metal Gear Solid V: The Phantom Pain
FOX. Metal Gear Solid 3: Snake Eater
Foxhound. Metal Gear Solid
Kill Count. Metal Gear Solid V: The Phantom Pain
Militaires Sans Frontières. Metal Gear Solid: Peace Walker
Mosquito Stinger Force. Metal Gear Solid V: The Phantom Pain
Outer Heaven. Metal Gear Solid: Peace Walker
Rogue Coyote. Metal Gear Solid V: The Phantom Pain
Zero Risk Security. Metal Gear Solid V: The Phantom Pain

There are a lot more PMC's/Units, but their logos won't fit BT or are simplistic black&white logos, making hard to see/edit. Sorry, Praying Mantis fans. I tried.

Updated for game version 1.0.4

Installation

A. Easy way -- NO other mods

Extract the BattleTech_Data folder from this file into the game main folder (Wherever BattleTech.exe is located). You'll be warned about overwriting folders. Do it. VersionManifest.csv is the only file that will be overwritten.

B. Manual installation -- Other mods installed, VersionManifest.csv is not vanilla

Extract the .dds files from this file (BattleTech_Data\StreamingAssets\emblems\player) into the corresponding folder.
Manually edit VersionManifest.csv (BattleTech_Data\StreamingAssets\data) using notepad, adding the following lines in the PlayerEmblems section (second to last section, just before BackerEmblems, around line 7550)

WARNING. Game patches will make the VersionManifest.csv outdated. I recommend you get comfy with editing that file, because probably I won't keep updating the mod forever / on time. 
Spreadsheet editors (Excel I.E.) will make working with .csv files at least prettier. You won't have to deal with commas.
