I’d like to see the option to see bipods show up for assault rifles and sniper rifles.
I’m thinking along the lines of an ability where if you are behind cover, you can take a shot that does not step out of cover, but instead braces itself against the cover for a much more accurate shot.
Downsides would be having a very limited free aim zone, ie rather than 360 degrees, limited to a 120 degree centered on the cover, and using an extra 25% of your TUs (longer to set-up and get back into cover using a bipod)
