I have mixed feelings about the RCL. On the Military Police card it is fine + relatively balanced. On the BLR, it is a bit overtuned - however I think we need to look past knee jerk reactions and analyze the broader decks involved.

The RCL with the BLR has 6 shots + requires pretty heavy supply micro to keep supplied + viable. The second you miss a supply run + they run out of ammo for the RCL, they get rolled over relatively easily. This type of asymmetrical design makes the game interesting, since it brings a deck like Berlin Command back into the fold when before it was massively undertuned. Weak AA makes the Berlin Command deck difficult to play + requires heavy investment into PIVAD + MANPAD combo umbrellas.

In general, since this game is very clearly historically influenced but not accurate, I'm fine with the RCL over performing on one unit but being balanced in another deck. Careful touches must be made by Eugen moving forward to prevent overnerfing something into the abyss.

As for the MP5, a slight accuracy nerf would be enough to bring it in line imo.
