Neepster Posted August 14, 2007 Share Posted August 14, 2007 Let me preface this by saying it is in the demo. However, I just witnessed something I am not all sure is feasible. An M1A2 was hit by TEN, count them, TEN 125mm main gun round from multiple T-72Ms from less than 200m in less than 60 seconds (granted, in the frontal to side arcs) and did not die. Instead it methodically killed my T-72Ms as if it were the easiest thing in the world. Now, I know the M1A2 is incredible. Probably the best tank in the world (with the possible exception of the Leopard 2A6). However, this seems excessive to me. We aren't talking a gun that is underpowered here, it is a 125mm 2A46 with a muzzle velocity likely over 1600m/s... Speaking of this, since the M1A2 has Chobham armor, how does CM2 do the armor penetration modeling anyway? Is there a separate post on this? 0 Quote Link to comment Share on other sites More sharing options...
jomni Posted August 14, 2007 Share Posted August 14, 2007 Not me. In my demo game, 3 M1 Tanks bites the dust and one gets immobilized. 0 Quote Link to comment Share on other sites More sharing options...
Guest Posted August 14, 2007 Share Posted August 14, 2007 You know, this whole thing is reminiscent of some problems I've seen before... I wonder if a few variables are being given random values unintentionally? Or it's intentional and the random number generator is bad? People's results seem to vary so much. One player has 1 in 4 decent QBs. Some players have an M1 survive under a barrage of 125mm fire, while another has three die immediately. My infantry performs wonderfully, then gets slaughtered in the same scenario and situation twenty minutes later. Yeah, there's luck, but all of our experiences seem to be all over the map. I wonder if it could be something so simple. Unlikely. Weird, though, isn't it? 0 Quote Link to comment Share on other sites More sharing options...
metalbrew Posted August 14, 2007 Share Posted August 14, 2007 The game underrates the Syrians currently. The Syrians usually fire HEAT at M1s rather than APFSDS. They rarely fire their ATGMs at all. A prepared Syrian fighting force would not fire main gun rounds at M1s unless they had clear side or rear shots. They would fire the ATGMs. If they chose to fire main gun rounds at all, the only choice they should make is APFSDS. Of course, being only 200m away may have meant that the ATGMs were too close to fire depending on the T72 and model of ATGM they carried. With all of that being said, the M1 should be able to easily live through 10 hits from the 125mm gun with high quality munitions as long as the rounds always hit the frontal armor. 0 Quote Link to comment Share on other sites More sharing options...
JonS Posted August 14, 2007 Share Posted August 14, 2007 Abrams are essentially invulnerable over the frontal arc. You can cause damage to tracks and gun over this arc though. Abrams are reasonably easy to kill from the sides and rear. 0 Quote Link to comment Share on other sites More sharing options...
Battlefront.com Posted August 14, 2007 Share Posted August 14, 2007 The Syrian APFSDS are useless against the front of an Abrams, so they fire HEAT in the hopes of causing some sort of damage. Flank and rear shots... totally different story. As with CMx1, the ballistics are calculated very deliberately. Only when there is a marginal chance of penetration does CM "roll" to see if it gets through. Same was true for CMx1 penetration changes. Unlike CMx1 all armored surfaces are tracked in more detail in CM:SF. Therefore, you will see more variation on things like flanks because hitting the side of the turret, side of the hull, or side of the lower hull makes a BIG difference sometimes. Depends on angles and what not as well. Steve 0 Quote Link to comment Share on other sites More sharing options...
John Catsack Posted August 14, 2007 Share Posted August 14, 2007 I have yet to see a syrian tank fire APFSDS. Even against the sides and rear of M1s and against other syrian tanks. They'll fire every other type of round, just no AP. 0 Quote Link to comment Share on other sites More sharing options...

The inverted T below the Abrams main gun and in the vicinity of the driver's hatch should be vulnerable to a well placed APFSDS. At least the Russians say this is vulnerable. Is the inverted T modeled in the game? What's going on with the reluctance to use the only weapon they have that can kill the Abrams (ATGMs)? 0 Quote Link to comment Share on other sites More sharing options...
mocdra Posted August 14, 2007 Share Posted August 14, 2007 Generally the East built 115 or 125 mm Sabots are less effective as West Guns. Less Accuracy,Range and Armor Penetration Values. The Rheinmetall 120 mm Gun of the Leopard 2 and the M1 has a Muzzle Vel. of 1600 m/s and a effective Range of 3500 m. Some Hits of m1a1 penetrates 2!T72 staying side by side behind a Sand Wall at once In my Opinion East AP Shells (APFSDS Rounds an HEAT Rounds) are not able to penetrate the Frontal Turret Armor of the most Western Tanks The Front Armor of the M1a2 is very massive. 900mm sightable thickness. In the frontal Armor is included a heavy DU Plate then 2 Layers of Chobham Armor and a kind of Bulkhead Armor( Like the Triangular Sections on the Leo2a6). All that is mantlet by heavy reinforced armor. In the Inside is in the Crew Compartement a Spall Liner. The Frontal Armor is able to withstand several Hits of the older Russian AP Rounds (up to t80 guns). The inverted T below the Abrams main gun and in the vicinity of the driver's hatch should be vulnerable to a well placed APFSDS. At least the Russians say this is vulnerable. Is the inverted T modeled in the game? The inverted T below the Abrams main gun and in the vicinity of the driver's hatch should be vulnerable to a well placed APFSDS. At least the Russians say this is vulnerable. Is the inverted T modeled in the game?I believe that it is modeled, but the most Shells hits the Front Turret Frames and not the Hull . Somtimes a Hit gets in the Gun Mantlet causing a Gun Jam but not more. Some Front Arc Hits downhull causing Immobilitys due Track Hits. Driver Hatch Hits or Upper Hull Hits are not occured in my Missions or not implementet in the Armor Model i think.

Flank and rear shots... totally different story. In the Allah's Fist scenario, a single surviving Abrams was put out of action by a lucky shot of a T-62MV firing with HEAT. The M1 was not destroyed, but it couldn't move and fire, so I used it for some target practice with the rest of my T-62MVs. The range was about 600m. I fired off all available munition, and indeed the Sabot did not penetrate from the front, it just bounced off. The ATGM's exploded but also didn't destroy it. Finally I drove up to the M1 and around to his back and killed it with the first shot right up is a.. - anyway, until then I also didn't like it when my Syrian tanks would refuse to fire Sabots at the enemy, but now I've completely changed my mind. It really seems that HE and HEAT rounds have the best chance to do some damage to an Abrams from the front. 0 Quote Link to comment Share on other sites More sharing options...
Nemesis Lead Posted August 14, 2007 Share Posted August 14, 2007 Funny--I had a couple M1A2s destroyed by T-55s at 100 meters. Frontal shots. That surprised me. 0 Quote Link to comment Share on other sites More sharing options...
Battlefront.com Posted August 14, 2007 Share Posted August 14, 2007 Charles just downgraded the Abrams frontal armor (ack... I can't remember which surface) a little bit in terms of resistence to certain shaped charge weapons. It probably won't make any practical difference, but there could be a situation where something like an RPG-29 could get through. Very unlikely though. The reason for the downgrade was seeing two Challenger 2's knocked out by RPG-29s. The Challenger 2 uses a similar armor to the Abrams, but there are slight differences in the properties and composition. Also angles and thicknesses are different as well. Anyway, that plus something else made Charles guess that he over calculated the ability just a little bit (less than 10% IIRC). Problem with all this stuff is we can only guess at what the values should be since nobody knows what the real values are. The information is classified and there are hardly any battlefield examples to draw upon and most of those are on much older models of Abrams. There are also no materials tests like those conducted during WWII to glean info from. It's all "best guess" stuff. Steve 0 Quote Link to comment Share on other sites More sharing options...
Neepster Posted August 14, 2007 Author Share Posted August 14, 2007 After reading the wiki article for the M1 http://en.wikipedia.org/wiki/M1_Abrams Particularly the armor part, I am less concerned that this behavior is unrealistic. Sounds like even the M1 has trouble killing the M1 in real life from the front and that there are documented cases of multiple APFSDS rounds to the frontal armor not penetrating... I guess I will make sure never to attack them from the front then... 0 Quote Link to comment Share on other sites More sharing options...

Neepster Posted August 15, 2007 Author Share Posted August 15, 2007 Hmm... that sounds rather optimistic unless they are comparing it solely against tanks even newer (I think the Chinese have the Type 99 and the Russians have the T-90)... I read something similar in the mid 90s as well, which obviously wasn't true against the T-72s and T-80s of Saddam... 0 Quote Link to comment Share on other sites More sharing options...
John Kettler Posted August 15, 2007 Share Posted August 15, 2007 Steve, Don't know whether it'll help or not, but I found a MUSEUM ORDNANCE in which an Iraqi T-72's composite armor array interior is exposed. Also, I find it wonderfully ironic that the Russians are allowed full details of the original Chobham armor (via Willy Brandt's defense minister), but even though the vanilla M1s with same are being scrapped under a classified contract (learned this on a Boneyards episode), we don't even get to see the obsolete system. BTW, www.warfare.ru has tons of great material on systems directly pertinent to CMSF and modules. Also, relatively easy to hide tank ammo upgrades can make a big difference, even with older tank models. Call the jump from hardened steel to tungsten or even DU worthwhile! Note, too, the marvelous detail on the Kontakt V ERA system, to include an ultra high speed radiograph of the system while defeating a HEAT round. http://www.warfare.ru/?lang=&catid=314&linkid=2390 Regards, John Kettler [ August 14, 2007, 09:34 PM: Message edited by: John Kettler ] 0 Quote Link to comment Share on other sites More sharing options...

Flanker15 Posted August 15, 2007 Share Posted August 15, 2007 I don't know how strong it is but I had a M1 ignore 5 AT-4 hits to the area of the turret ring just under the barrel. I usually think of that area being the weakest place on front turret armor but I could be wrong, also shouldn't the hits atleast damage the gun? 0 Quote Link to comment Share on other sites More sharing options...

Flanker15 Posted August 15, 2007 Share Posted August 15, 2007 Syrian ATGM design. Also for people being unhappy about their T72 using HEAT against M1s at least yours don't fancy HE rounds as an AT weapon, mine do (4 HE shots into a M1 before changing to HEAT is my record)! 0 Quote Link to comment Share on other sites More sharing options...

Three CR2s have had their protection compromised - 1 blue-on-blue where a HESH round hit the open commander's hatch, 1 RPG-29 casualty and one severely damaged by an IED. 0 Quote Link to comment Share on other sites More sharing options...
