I really don't know where you got your information from, but I don't believe it. The following specs on the BMP3 were taken from:
http://idex.janes.com/landforces_data/bmp3details02.shtml
and
http://www.army-technology.com/projects/bmp-3/
About the 9M117:
The complete round weighs 24.5 kg with the missile itself weighing 17.6 kg for the BMP-3 version, muzzle velocity of 370 m/s and maximum range of 5,500 m, although earlier sources quoted a range of 4,000 m.
So not 6 or 7km range but 4 to 5.5.
And about armor penetration:
The original 9M117 missile was claimed to be able to penetrate between 650 and 700 mm of steel armour but more recently another missile, the 9M117M with a tandem warhead has been developed. This is claimed to be able to penetrate up to 550 mm of steel armour with the original missile now stated to be able to penetrate only 275 mm of steel armour.
FAS states about the TOW tow being able to penetrate 800mm+ of steel armor and having a maximum speed of 329(TOW2 and TOW2A)m/s. So less range and speed for the tow, but much better armor penetration
Also the fire control system and night vision equippment seem to be not that good, since Kuwaits and UAEs BMP3 are fitted with French thermal imaging systems and FCS.
FIRE CONTROL AND OBSERVATION
The fire control system is automatic with manual override for both gunner and commander. It includes a 1V539 ballistic computer, 2E52 electromechanical armament stabiliser and 1D16 laser rangefinder. The gunner has a 1K13-2 main sight, a combined image-intensified day/night sight and PPD-1 standby day sight. The commander has a 1PZ-10 day sight and TKN-3 combined day and image-intensified night sight.
The BMP3 features only Image Intesifiers, not thermal imaging, which is a drawback.
Also the weight of 30t for the M2 is too much. M2A1 is at about 22t, the latest versions at about 28t. So power to weight is about 21 hp/t for the M2(600hp/28t) and 27 hp/t(500 not 450hp/18t) for the BMP3. Though the BMP3 IS more maneuvrable and faster(about 70kph max speed to about 60kph for the M2) the difference is not comparable to a Tiger vs Sherman.(BTW: German tank crews were able to destroy up to 20 enemy tanks before getting blasted themselves - I suppose masses of Shermans were more important than their mobility.
Also the stated range of the 100mm main gun of 7kms is wrong. And it is a low-velocity/low-pressure gun.
There are 30 rounds of high-explosive fragmentation ammunition carried for the 100 mm gun, 22 of which are for ready use in the automatic loader. This round has a maximum range of 4,000 m and a muzzle velocity of 250 m/s.
Another interesting fact is the following:
According to Russian sources, the BMP-3 can engage a target at a range of 1,000 m in just under 3 seconds with a 90 per cent accuracy. For a 2,000 m range however, this takes 14 seconds.
So to effectively and fast engage targets, the BMP3 has to be close enough.
Now this all is not intented to bash on the BMP3; in fact it's among the best IFVs I ever heard of, but it's not the wonder vehicle you claimed it to be.
As far as combat goes, the BMP3 didn't see too much AFAIK. The M2 Bradley series were in DS, and according to:
http://knox-www.army.mil/school/tid/dli/accc_rc/equipment/bradley_fighting_v.htm
The vehicle's reliability, survivability and lethality has surpassed initial expectations. Of the 2,200 Bradleys involved in Operation Desert Storm, only three were disabled. In fact, more enemy armored vehicles were destroyed by Bradleys than by the Abrams Main Battle Tanks!
Impressive enough?
Whatever, guess that post is long enough..
Gholam:
The role of an IFV is to provide fire support to infantry and give it better anti-armor capabilities - this includes the possibility to fight enemy IFVs; of course BMP3 and M2 were not solely designed to fight each other, but they might have to.
What is that 7.62 caliber thing you talk about? Is that caliber in mm cm inch? Against which tank did they use it?
Apart from that DU is pyrolythic(or so) which means it ignites itself - and against the Russian autoloaders hot fragments are a real danger; most Iraqi tanks lost their turrets when the ammo in the autoloaders blew up after being hit. So I suppose hot fragments against infantry and the tank crew inside might be effective enough.
Effectivity against infantry might be a point against the M242 compared to a 100mm gun, but in fact ACs do quite nice against infantry with HE rounds because of their fire rate - though the 100mm is better, no question..
Last thing for now: why does everyone think gun ports are good?
M2A1 had them, and they were removed because the were pretty useless and weakened the armor of the vehicle. In fact a gun port is just a piece of armor that will be penetrated if hit.
And you forgot to add the 30mm AC to the anti-infantry firepower. Also this is ideally, since 2 MGs just fire to the front, so in fact you have a 100mm gun, a 30mm AC and a 7.62mm MG that can be turned to any possible target. Just forget about the ARs in the gun ports..
