It's awesome to hear that you found Star Army through HarperMadi and that mechs are what interested you in joining. Mechs can be really exciting to play with in roleplay, so I'm sure you'll have a blast.
Since you're new to text-based roleplaying, don't worry, we have a friendly and supportive community here who will be more than happy to help you get started.
As for your cool RP idea, I love the concept of piloting mechs in a mech squadron or being part of a mech company with a generous budget. Both ideas sound like a lot of fun, and it's great that you prefer a chill and enjoyable atmosphere.
I hope you have a fantastic time in Star Army, and don't hesitate to reach out if you have any questions or need any assistance. Enjoy your roleplaying adventures!
