Infantry Survivability

[Muhail2]

Infantry losses which took weeks to achieve. In SP you can do it in minutes. The game is far, far deadlier to infantry than the Kursk battles were.

I've written at least twice, why the combat in SP is deadlier than combat in real life and why it IS realistic. Consider re-reading.

That's quite a long range to fire at individual soldiers. Don't expect too many casualties at that range.

At individuals, in woods - maybe. But surely not when firing agains a 10 men squad or a heavy weapon team.

The game system use a hit determination first and then checks to see if the hit actually does any damage

Yes, and somewhere in that system a coefficent is put wrong or a glitch happens to be.

No, the 152mm gun should be considerably less effective against infantry in direct fire at those ranges compared to the mg's. You seriously believe that the 'main' gun was/is the primairy weapon for direct fire use against leg infantry???

You seem to completly miss the point of HE weaponry. While a time-to-corpses ration of MG firing at advancing infantry in open maybe better than of HE weaponry, it can't do one important thing - destroy or negate cover. In reality infantry always tries to hide behind some cover, both in advance and defence. MG can do nothing to a trooper behind a rock or in a little hole, even a fallen tree can save soldier's life. And HE blast will destroy both cover and hiding soldier, and chances are that one of the many high-speed fragments (you do remember than most of aforementioned weapons are HE-FRAG?) will find it's way to some other soldiers. Or a shockwave will do the job.
This raises another question: why does HE effect suffer so much when firing at infantry in houses or woods?

AGL's and autocannon should be in the same order of effectiveness as mg's, maybe just a little less effective but not much.

Stupid soviets, why they were so happy about their AGLs and tried to install one on every BTR in Afghanistan when it's not effective? :)
AGL can over-shoot obstacles - the thing which standard MG almost never will do - or place flanking shots at the cover to get the soldier with fragments.

Units need to be balanced in points against all other units in the game in all possible tactical situations

Yes, they must be balanced - but the game is far from balanced now. A mentioned platoon of tanks can only effectively destroy enemy armor. A tank barely has ammo to rout an infantry platoon, especially if he can't move too close risking getting an RPG round in side.
And mentioned battalion of infanty can fight with almost any targets at most ranges. ATGM will wipe out tanks easily, personal RPGs will make short work of light armor, MGs will take out supporting infantry and personal SAM launchers will make pilots' lives more exciting. With a little increase in cost to buy APCs instead of trucks they will be even more mobile then tanks. A battalion of infantry is a unit fit for any task, while a tank platoon is no more than armor-sweeper. It does it's real-life job of supporting infantry with fire exceptionaly bad.
And both have the same cost.
I don't sense balance in here.
