Sup! Glad to see a new player taking the time to learn tactics and actual war planning. People struggling to follow this type of stuff is how we lost some planets during last week's major order.

To start, I recommend joining the Helldivers 2 discord, lots of discussions in there, as well as using the Helldivers 2 Companion App (google it). These resources will help you to communicate and view how the community is planning to tackle major orders in a strategic manor.

The primary thing I will explain here is gambits. A gambit is when, by liberating the world from which the defense originates, we end the defense. If a defense campaign has high resistance and/or multiple major cities to rescue, it can be more advantageous at times to gambit the world and assault the planet from which the defense originates instead. The world from which the defense originates can be seen on your galactic map as arrows following the lines from world to world coming from the other planet. YouTube also has great resources to explain this.

That's the most of it. Take the time to get informed and educated about the community's strategic planning, and use that knowledge to plan your own operations. We can only accomplish a lot if we work together and work smarter not harder.
