Arrow variants. Having different arrow types that would replace one of the gadgets, you can choose one extra arrow type. Reaching over your shoulder would grab that new arrow type, some of these can include:

Explosive Arrow: Arrows that have impact explosive effects, deal damage to buildings and vehicles but not very effective on ground troops.

Tracking Arrow: Arrows that allow for talons to track onto it for 10 seconds . Can be fired at ground vehicles, buildings or even enemies and will ignore flares if attached to a helicopter. Will do no damage to enemies.

Sensor Arrow: an arrow that sticks into any surface and will beep and mark any enemies with a proximity, will do no damage to enemies.

Will hopefully be adding more ideas, this would make the bow and recon have more flexibility.
