Flexible unit

We are an English milsim unit. Our Operations are based in Iraq, Afghanistan, and other places! The operations are Zeus made missions but we also have auto-generated missions such as Dynamic Recon Ops and Liberation.


We are a semi-realistic unit and we are US Marines/Army based.
Two missions a week (Wed and Fri 18:00 CEST).


We in The Lost Battalion know that people have work or school to attend besides playing ArmA. If you can join at least one operation a month you are considered an active member in The Lost Battalion.

We have 3 servers running 24/7
One Operation Server, Training Server and Liberation Server
