Operation TREBUCHET First Contact

Operation: TREBUCHET First Contact is an expansion for the Operation: TREBUCHET modification for ArmA 3. It will be developed separate from OPTRE and will not affect the development speed or process of OPTRE. Unfortunately, it will not be developed as quickly or frequently as OPTRE, as it is mainly a side project and fan service. However, we will do what we can to fix glaring bugs and issues and add new content as it it is ready.
