None of the realism mods are tuned for gameplay. All of them make the MP44 overpowered and too accurate, making it difficult to choose any other weapon.

If you want a mod to inject a little realism into MOH, but still keep gameplay balanced, try this one.
[GLW]GenghisLAN MP Weapons Mod: http://mods.mohmatch.com/dl_manager/...on=file&id=139

I wrote it for my regular LAN party and we like it better than anything else out there.

The MP44 is still the best all-round weapon in the game, but not by much. You can kick ass with any weapon, provided you have skill and a little luck.

PS - Here's a bit from the readme file:
Description:
============
This server-side mod changes the weapon settings for multiplayer MOH:AA. The
goal is to provide balanced gameplay with more powerful weapons. Weapon damage
has been increased, accuracy and movement modifiers adjusted.

GLW isn't strictly a "realism" mod, we've tried to add to the excellent WWII
feel of MOH:AA. The changes make combat more deadly, but the values were also
tweaked for gameplay and feel, not historical reality.

The main changes are these:

-rifles are more powerful
-automatic weapons are more powerful, slightly less accurate
-rockets and grenades are limited to 3
-player movement speed is up a few percent, except machineguns which are
down a touch
