The Royal Marines MilSim Unit is an ArmA 3 Military Simulation unit that takes on the role of Royal Marines Commandos in a virtual environment. We aim to provide an accurate and enjoyable experience of what it would be like to be a Royal Marines Commando through a multitude of time periods, however our main focus solely lies with the modern day setting, with our unit being set up under the Future Commando Force Module. Despite this, some liberties have been taken in areas where we are either unknowledgeable, had to substitute equipment that is not available to us through modifications, or simply we have seen it suitable to change, to make it a more enjoyable experience for players compared to what the real life alternative is. As a unit, we have a huge focus on teamwork and promoting a healthy community environment. We often try to run out of hours events for fun, these will range from playing a different game together, running a friendly competition, just getting together to chat, to maybe even hosting a unit movie night. We regularly hold votes and discussions about what our members want in their events so anyone who has ideas of what they want is welcome to give suggestions or even run their own events in the unit. In Operations, we enforce a mild form of Roleplay in order to help immerse people into the roles they are playing. This means that everyone is expected to maintain a level of professionalism and keep to the task at hand, however, with that said, how could we portray the Royal Marines without a bit of Commando Humour? Nobody is expected to call their NCOs by rank nor call their Officers Sir or Ma’am. What is expected however is a level of respect for those in leadership roles and a willingness to abide by the Chain of Command we have in place.
