Not only does the Russian tank crew use American tank fire commands in a Soviet tank, they only use them correctly about half the time. For instance, they correctly yell "up!" when the round has been loaded, but the proper warning when traversing the turret is to yell "Power!" while they use "Traversing!"

The hand grip on RPG has black tape over the serial# in cave but not during the closeup just prior to Koverchenko's shot at the tank.

In the cave scene when Koverchenko is fixing the broken RPG launcher, he has it cradled in his lap. In the next shot, Taj is shown holding the launcher. In the next shot, Koverchenko has it in his lap again.

The searchlight on the turret and the canvas around tank main gun change back and forth from damaged (from nighttime Molotov attack) to undamaged several times.

When they are tying Constantine to the rock, the wrap around wire frame of his glasses has come off his right ear. A few moments later it is back in place around his ear (his hands are tied the whole time)

Russian tanks run on diesel, not Helicopter Av-Gas; even if it did, 20 gallons of fuel would be worth about 20 minutes in the tank, not a full day and night of operations.

The T-55 tank's crew is comprised of four men, not five as depicted in the movie. Indeed, it's impossible to accommodate five men in this kind of tank.

At one point the gunner pulls the trigger and the main gun fails to fire (a mis-fire) The crew begins yelling, "Cook-off!" and jumps from the tank to take cover. First - a cook-off occurs when a very hot breach causes a round to fire by itself, not at all what happened in this case. Secondly, a misfire is indeed dangerous because you don't know if the primer was struck or the firing mechanism failed. If the primer was struck, the round could still fire unexpectedly. On rare occasions a primer can burn slowly for a bit, then go off. The best place to be in that case is in the tank, clear of the breach. (if the gun does fire the recoiling breach could maim or kill you if you got in the way - such as while scrambling around yelling, "Cook-off!"). Jumping out is a bad idea too, because if the gun fires the muzzle blast will mess you up. So their drill was as wrong as it could be.

The helicopter in the movie was an Aerospatiale Super Frelon, which was never in use with soviet armed forces. However it bears a striking resemblance to the soviet Mil Mi-26 helicopter, therefore it was used as stand-in.

The women are conversing/speaking in Hindi, which is totally unrelated to the locale where Pushtu is the native language.

When Daskal is at the gun controls he manually traverses the turret to the left. As viewed from the outside of the tank the gun was forward and swinging around the left side of the hull. In the interior shot the azimuth indicator behind Daskal shows the turret is facing rear right and moving around the right side of the hull, 180 degrees opposite.

When the first round flies over the town and hits the hillside in the opening scene, a black dot can be seen at the exact spot of the fireball just prior to the explosion (pyrotechnics placed to simulate the explosion of the round).

During the close-up of Taj and the other rebels' feet as they run toward the tank, you can see the shadow of the camera and rigging casting down on them.

In the scene after Hassan and Mustafa are talking in the captured Russian helicopter, when the Russian tank is moving, pointing the main gun opposite to his direction, a shadow of a person is moving into the frame from the left.

There are several inconsistencies in Daskal's backstory. He mentions fighting the Germans at Stalingrad (1942-1943) as an 8-year old. If this is true it would make him 46-47 years old at the time the film is set. Also, he tells a story about being in a tank that was hit by an RPG in Mongolia. The Soviet Army never fought in Mongolia.
