Another not a proposal, but rather a concept of how to leave the BR system and preserve some historicity. So, I’ll get to the point:
We divide all weapons and equipment into 2 conditional periods, these are 1941-1943 and 1944-1945. This division also serves as a balancing value, powerful weapons and equipment fall into the late period of the war, regardless of the year of production and the actual time of participation in the war. Initially, I thought it would be possible to make two separate sections like the old companies, but I came to the conclusion that this is unnecessary, and the usual division into combat ratings will be enough:
Early period of the war BR1, BR2, BR3.
Late period of the war BR4, BR5, BR6.
BR3 and BR4 do not intersect at all.
Spread ±1BR.
The combat rating, as now, will be determined by the maximum BR of the weapon or equipment in the setup.
BR1 and BR4 are the weakest weapons of their period. Accordingly, BR3 and BR6 are the strongest.
Weapons from the Early period can participate in Late period battles in this case BR3 is equivalent to BR6. Similarly, other BRs. If they have the appropriate weapons. However, Late period weapons cannot participate in Early period battles.
I wanted to make only 4 battle ratings, but in the end I decided to add another one to better separate weak and strong weapons.
An example of implementation based only on weapons from the research tree:
USSR Early period 1941-1943.

The same should be done with tanks and planes, but as a rule, the newer it is, the stronger it is, so there shouldn’t be any major changes. Of course, there are some controversial issues, but nothing is insoluble. Thank you for your attention.
