Can we stop using standby loaded cannons?
Seriously, I'm totally tired of complaining. This was the case with the LATV4 30mm cannon from the very beginning. This gun is perfect, it just shouldn't be mounted on a reconnaissance vehicle. LATV4 respawn has a short cooldown and a large number of deployable vehicles, which is too malignant for an environment where heavy ground vehicles are severely limited at the time. But it's designed with the right idea, high rate of fire, slow overheating, low damage, and a large splash range. It is more suitable for IFV.
For the BMP2 and M3A3, both the original magazine gun and the overheating limit of the 2042 are good, and even to make a difference between them, it is only necessary to adjust the rate of fire and damage. The BMP2 can adjust the overheat limit to 15-20 rounds, increase the rate of fire, reduce damage, and adjust the amount of ammo needed to kill from 3-4 rounds to 6-8 rounds. The M3A3 can retain its current rate of fire and overheat limit of 8 or 10 rounds, and can reduce some damage if there is a concern that it will be too lethal.
My opinion is that IFV needs more suppressive firepower than precision kills. Vehicles are mostly the main threat units with large sizes, and they don't have many comfortable conditions to snipe infantry, especially if the IFV is a front-line support unit. Sacrificing sustained firepower and high damage at a single point brings a very low margin for error, and every shot needs to be accurately hit, otherwise there is no threat to enemy infantry. So if you want to be efficient in this firing mode, you should have a rear point, but doesn't this turn into infantry fighting on the front line and vehicles at leisure in the rear?
