The menus in battle are bad. The first-person squad order menu is hidden from most players, and no instructions on how to open it. The vehicle and off-map support menu basically paralyzes your character. The item select system makes it hard to quickly select equipment since there is no quick-swap like with weapons. There is also no method of asking for ammo, repairs, or anything else without a mic; even with a mic, the other person maybe on a different channel.

I tried the BF4 beta a while ago, and it reminded of how bad Dust's in-battle menus are. The way they manage to squeeze and organize so many functions on the controller (switch firing modes, turn on/off laser, switch equipment, spot enemy, vocal calls) in a sensible way gave me an idea on how to fix it.

the menu on the right d-pad button should be a radial menu that you have to hold the button to keep open. You should also be able to move while using it (just like item wheel). More importantly, i needs to be expanded to include squad orders (select quad orders, and get a sub-menu listing specific squad orders), and some system of making your character say built-in vocal commands (like "i need ammo", "i need repairs", and "get out of the vehicle"). Regarding the vocal commands, they need to trigger minimap icons to show the location of the requester as well as what is being requested; the "I need ammo" thing for example should show a flashing icon with an ammo symbol.

Now about equipment, equipment need to have their own button to tap to cycle through them, and to hold to open a wheel to select them exclusively. Not sure which button it should be; perhaps the overview map button since the start button opens up the map as well with the Neocom, or perhaps the player-list since it can be accessed from the Neocom as well.

Just use mouse & keyboard

Or in vehicles square and x are unused those can be used to cycle (square) and activate (x)
