Ok. My readers want max shoot & scoot capability on wheeled artillery vehicles? Then you want BAE's Archer

ARCHER’s armored cabin makes it safer to operate the 155mm mobile howitzer from inside the vehicle. ARCHER allows soldiers to provide long-range fire and quickly depart its position for increased survivability—to “shoot and scoot.”#ARCHER #howitzer #Eurosatory2022 pic.twitter.com/rUW0hShb98

Logistics is gonna have to be on point. I believe it carries only 18 rounds ready to go (need to check but no time). But if shooting and scooting is the key to survival then this is hard to beat.
