What is Blue Army?
1.
An early, dedicated follower of Aerosmith. Aerosmith remarked at a concert that their audience members wore overwhelming amounts of denim, and said they looked like a Blue Army.
You fight in the Blue Army? Hell yeah, I love Aerosmith.
2.
The more badass half of Red vs Blue. Theyre the ones who wear the blue armor!
Damn those Blue Army guys just beat our ass again, Private Donut!
