Happy new year! The heavy fireworks around us reminded me of artillery fire, so I decided to create this.

Edited with Audacity, sounds sourced from Company of Heroes.

I don't know why i uploaded this but the gunfire ambience is just so relaxing to listen too its because you usually hear it in some single player missions and most multiplayer levels. you can find this in your game files (PC version only), but you have to extract the iw files, ex. iw_14.iwd. iw_01-iw_11 are just images and iw_14-iw_20 are all sounds in the game.

Over 10 minutes of random radio chatter from the game files. I don't know how it compares to real-life military comms.

Some references to help comprehend the chatter:

http://en.wikipedia.org/wiki/Military_grid_reference_system

All of this stuff is located in localized_english_iw02.iwd
Extract it and look at sound\battlechatter\US\bursts
