I couldn't find this anywhere else on the internet, so here it is! The controller layout for Helldivers 2 is pretty intense. Visualizing it instead of mentally mapping it from the in-game button list can make it easier to learn all the different functions you need to spread democracy.
A big thank you to PadCrafter for creating such an awesome tool! It made creating these reference controller layouts a breeze. You can view the layout right here.
And many thanks to Arrowhead Game Studios for making this phenomenal game!
Also for reference, here are screenshots of the in-game controller keybind menus:
