A lot of these responses are acting like the OP said RNG should be removed from the game. Only morons ever suggest that idea. The title is "Lets fix RNG". At least as far as I get a feel from playing is, there is a lot more random outcomes of minor engagements that should just go one way. I think that is the point the OP was trying to make. Some engagements that even should be a roflstomp end up going the other way, and way more often than vCOH. This is what makes it seem more like making units, throwing them at other units, and watching while flipping a coin sometimes. Maybe my luck is just worse and this happens more to me, but meh. Cuz dat
sniper video was mine, tell me that's happened to you.

It's a perfect example of this as well.
This may also be from more of a lack of factors that contribute to the outcome of engagements. Like the cover system being less of a factor meaning positioning is less important, and the absence of units like bikes/jeeps/kettens pushing and other factors that the player can control to change the outcome of an engagement from one that might be a straight up loss. It was way more fun to watch a game in vCoh and have these tools at the players disposal to change the outcome of an engagement. These were required micro and skill. In COH2 it seems more like you either run in a building or gamble on your riflenade, nades, or moli's to turn an engagement, or pray on the rng coinflip. The lower raw infantry damage doesn't help here either. It may not really even need to be rng that needs to be addressed so much as these other factors taken a look at. Then rng would play less of a role on its own.
Random squad wipes from single mortar rounds and normal soviet mines also add to this frustration, however that is another issue slightly different.
