Based on the recent “New Year’s Breakthrough” pacific war event squads, this is my suggestion for a similar event for berlin instead. These event squads would be notably different to other event squads, as all squad members would have the same gun. The axis squad is a Volksstrum squad desperately using whatever weaponry they still have, while the allies squad utilizes multiple Thompson submachine guns imported through the lend-lease program.
Allies - 5 man Thompson Assault Squad
Over the course of WW2, the United States exported approximately 137,000 (~8% of total production) thompson smgs to the Soviet Union. These Thompsons were used in every major battlefield on the eastern front, and one of them is even a campaign unlock in stalingrad.
Three main varieties were sent through the lend-lease program, the m1928a1, m1, and m1a1.
The idea for this squad is that some red army soldiers have been issued these Thompson submachine guns and each soldier has a preference for one of them. So the composition of the squad would be something like this:
4 Assaulters - 2 m1a1, 1 m1 and 1 m1928a1
1 engineer - 1 m1

Axis - 9 man Mixed Weaponry Volksstrum Squad

During the final hours of ww2, Germany attempted to rely on the poorly equipped Volksstrum to help hold the Soviet Union back. The Volksstrum is already portrayed in the game, as a few campaign squads and 1 premium. However, none of these options really capture how poorly equipped the Volksstrum were near the end of the war without the player purposely giving their squads bad weapons. The weapon inventory of the Volksstrum in January 1945 would also really allow a mixed weaponry squad that is impossible for campaign at the moment.
If you want to take a moment to browse the inventory, here is a link to it
Essentially, you could create a rifle squad with old german, italian, french, russian, belgian, austrian, czech, dutch, and polish guns. A true display of weapon variety that would make for a very interesting squad. The squad itself would also have some panzerfausts in it, the Volksstrums primary role was anti-tank. Not to mention that the panzerfaust is unlocked really early anyway (level 6).
I suggest a squad composition somewhat similar to this -
Engineer - gewehr model 1898 (ingame already)
Bomber 1 - Carcano m1891 (ingame already)
Bomber 2 - Berthier Carbine (ingame already)
Soldier 1 - gewehr 1888 (not in game to my knowledge)
Soldier 2 - Carcano m1891 (ingame already)
Soldier 3 - kar 98 (ingame already)
Soldier 4 - Berthier Carbine (ingame already)
Soldier 5 - VZ. 24 (ingame already)
Soldier 6 - Mosin-Nagant (ingame already)
This is not to mention all the last-ditch weapons that were produced in small numbers in 1945. I mentioned many of them in this post here -
A mixed weapon squad with the german-made last ditch weapons instead of the left-over bolt action weapons would be just as fun imo. Getting both squads at some point would be ideal.

Concluding Remarks
These squads would be interesting and not create almost any new weapons, so they would be easy to make for the devs. I am interested in what you guys think about mixed - weapon event squads.
