Without knowing quite where you're going with this mission, it's difficult to be sure what sort of advice or suggestions you're after. Is it a practice excercise or are you aiming to submit it for review?
Anyway, testing version 0.95. At least I think it was v0.95 because the change in number was not reflected in the readme (or on the overview).
I generally approve of the changes you've made: the hyperlink in the Plan works, amongst others. I played in Veteran mode and found it to be very tough but beatable - that may need a second opinion though.
I would suggest that you give the attacking forces at least one more waypoint, so that once they flank the line, they try to roll it up.
I warned you there may be hard work involved, and if you want it, it starts here: East Machine Gun Emplacements
At the moment, you've placed M2(East) which already have a gunner in them. On seeing this, the Americans aim for the gun itself, eventually killing the gunner, but they continue shooting at the gun until it blows up. This has two effects: Americans expend effort shooting at an unoccupied gun rather than Russian soldiers; but, on the other hand, it adds a lot of atmosphere as bullets fly over the sandbags and hit the ground some way behind. (If you've never done it, look South while the battle is raging).
The alternative would be to place empty M2s with a few more soldiers nearby. Then you'd use a Script to man the machinegun - once the gunner is killed, another takes his place.
I thought there was such a script in the Editors' Depot, but I can't find it at the moment. Let us know if you're interested. As I hope I have warned, it may change the dynamic of the mission somewhat, after which it will need re-balancing, and then you'll get another idea ... and so it continues ...
