Preventing reduced damage

[Luft08 27]

I was testing one of my coop missions on a dedicated server with a few friends.  I died quickly so I was watching the other's play. One player was repeatedly hit by gun fire but just kept going. It happened so many times that I though maybe I had disabled damage for the unit. He did finally die and later checks showed that damage was enabled.

 

So I looked through the difficulty settings and found a "reduced damage" setting. That appears to be what was happening but only to him.  My question is: If a player sets reduced damage on HIS Arma does the dedicated server change it back or does he play with an unfair advantage?  If so how do I enforce my server's difficulty settings on player's PCs?

 

Thanks.

Players difficulty settings are forced by server in multiplayer.
