Hey guys! This is going to be our very first fanfiction so please, save us some slack. Yes, I said "our" because this was a group effort by me and a couple of guys at our halo role playing forum called "YappashaloRPG". We decided to do a Halo/Battle:LA crossover, set 5 years after the events in the movie Battle:LA and during the events in Halo 3, as a little fun side project in addition to our main halo mission that we currently have going on. Anyways, formalities gone, we at YappashaloRPG present to you the timeline from what happened since the movie "Battle:LA"

END TIME LINE

NOTE: I've focused on the US for the majority of the timeline because that's where the main story takes place. So, sorry if you guys are hoping for a global fight. However, if you guys want, we can create a one-off chapter focusing on some soldiers/marines fighting in other parts of the world.
