This suggestion will affect the following tanks
Currently, these tanks use M72 AP shells for their 75mm guns. Which is a solid AP shell without high explosive fillers.

Normally, when it hit enemy tank, things go like this:
In most cases, your first three shells will kill one enemy each time, and when you hit the right spot, it will kill two crew. It can never achieve the same effect as APHE shell, and cannot even compare with 45mm and 50mm APHE shells.
As the number of enemy tank crew decreases, the killing efficiency will become lower and lower. In the most extreme case, you may need 4-5 additional shots to kill the last crew member (you cannot ignore it because it still has the ability to shoot back)
The loading time of Grant and Lee’s 75mm gun is 4.8 seconds, but the installation position is bad, and the target of the vehicle itself is way to huge, making it vulnerable to preemptive strikes(Considering that it has a larger ammunition rack, the chance of ammo detonation will be greater).
The M8A1 has a loading time of 5 seconds and excellent maneuverability, but it is a open-topped vehicle that is easily destroyed by high explosive shells and aircraft cannons.
The M24 is currently the most “standard” tank who still firing M72 shell, but its loading time is 6.5 seconds. When it fires 2 rounds, other BR2 tanks are already sufficient to fire 3-4 shells.
Compared to their enemies in BR2, the Panzer IV has equally poor lethality, but a much faster firing rate(3.3sec reload), while the Panzer III J1 and PUMA’s 50mm guns have better lethality while firing faster(3.7sec reload). Ho-I lacks an advantage in anti tank firepower, but almost all shells can be used to against infantry (it has an APHE shell with 470g charge; once penetrated, it will kill everything) while having much better survivability (especially when facing Bazooka, it can withstand many shots).
Providing M61 shells to these tanks can improve the problem of insufficient AT firepower of the USA BR2 tanks. Of course it brings some problems, such as the need for Ho-Ni III down to BR2 to improve the AT firepower of Japanese BR2, but that’s another topic.

Any way, the M72 shell is no longer suitable for use due to its bad performance, and USA BR2 tanks need a better APHE shell.
