The Battle of Phase Line Bullet. The battle the Iraqi's won.

So you think that Gulf War 1 was easy?  Let me introduce those people to the Battle of Phase Line Bullet.  via Wikipedia.

The Battle of Phase Line Bullet was one of the clashes which led to the destruction of the Tawakalna Iraqi Republican Guard Division, on February 26, 1991, by a simultaneous attack of two US Armored Divisions (1st and 3rd), an Infantry Division (the 1st) and the 2nd Armored Cavalry Regiment.
The battle was one of the rare examples of a US armored force repulsed by a screen of Iraqi entrenched infantry, APCs and Iraqi T-72stanks during Desert Storm. The incident involved American friendly fire casualties.
BackgroundThe initial skirmishes between American and Iraqi Republican Guards units took place earlier that day around pre-established line 73 Easting, some 30 miles west of Wadi al Batin, where the 2 ACR managed to destroy two Iraqi Armored Brigades. The skirmishes in this sector were still going on when the 3rd Armored Division, positioned north, made the first contact with a brigade of the Tawakalna Armored Division around 3:30 PM.[1]Weather conditions were extremely poor, hampering visibility and identification of targets.
Flank screen maneuverAs the usual practice for armored reconnaissance, a troop of M3 Bradleys (Alpha Troop), belonging to the 4th squadron of the 7th Cavalry Regiment, was scouting ahead of the main tank force. The flank screen maneuver took place along the southern boundaries between the 2 ACR and 3rd Armored Division operational areas. Task Forces 4-34 and 4-32 were advancing from the rear. The general movement of the US forces followed an eastward direction. The fumes of hundreds of oil wells set on fire by the Iraqis, combined with an intense shamal, forced the US vehicles to use thermal sights.[1]Surprising contactAt 3:00 PM, the 14 Bradleys strong troop received information from the GHQ of the 3rd Armored Division that no enemy unit remained between them and the Kuwaiti border. Suddenly, they found a screen line of Iraqi APCs straight ahead, barely 300 meters to the east. The poor weather, along with burning oil fumes, reduced the visibility conditions to almost zero.[2] The enemy screen line was part of the 9th Armored Brigade of Tawakalna Division.
US Abrams tanks from TF 4-34, positioned in the rear echelon, fired in support of the IFVs, destroying at least one T-72 and several Iraqi APCs. They also hit three Bradleys (A-24, A-31 and A-22), with two American KIAs.[2] The 2 ACR also became entangled in the fighting from the rear right.A burst of small-arms and heavy machine gunfire, RPGs and Sagger missiles erupted. Initially, the American commander thought they were engaging dismounted infantry supported by BMPs, but later he realized that they were also receiving main-gun tank rounds.[3] The US vehicles retaliated by firing TOW missiles, 25 mm cannon and machine gun fire. The contact lasted for about two hours, until the Bradleys, battered by enemy and friendly fire and running out of ammunition, were forced to withdraw.[4]Another Bradley (A-36) was first disabled by a 12.7 mm round from an NSVT heavy machine gun which penetrated the transmission[5][6]and later shattered by a large caliber shaped charge impact in the turret's front.[7] Bradley A-35 also took some damage from a mix of ricocheting 12.7 mm bursts and indirect fire, but was able to be driven out,[8] while A-33 suffered two injured and its radio station hit by 12.7 mm fire. During the process of rescuing casualties from A-24, Bradley A-26, commanded by Sergeant Major Ronald Sneed, was near-missed by a T-72 main round, which spattered the vehicle with splinters.[9][1] While providing cover for A-21 who was attempting to assess the situation with A-36, Bradley A-22, commanded by Staff Sergeant Meyers, was struck in the turret by an M-1 tank from TF 4-34 resulting in one KIA.[10] The gunner of A-24 was also killed by a friendly tank round.[11]The disabled A-22, A-36 and A-24 were left abandoned on the battleground, while A-31, although heavily damaged, was able to pull back.[12] All the remainder Bradleys were raked by machine gun fire and shell splinters, but they were still marginally operational.[13]AftermathThe U.S. forces were unable to find a breach in the northern Iraqi lines until the first hours of February 27. That morning, the 7th Cav scouts found the hulls of 18 APCs, mostly BMP-1, and six T-72s disabled or abandoned by their crews. The clash is one of the few recorded actions where a US assault was fenced off by Iraqi dug-in armored vehicles. The commander of Alpha troop, Captain Gerald Davie, later acknowledged that the cause of the fiasco was that "we were ten times too close to the enemy than we would choose to be".[14]

Environmental conditions played a major role in this battle.  What happens when the next battle is fought in the rain, under the jungle canopy and fog commonly found in the Pacific?
