The SUM is particularly well-suited for setting up ambushes or flanking shots in urban combat, which tends to occur at short ranges and where the poor gun depression is less of an issue. The ready availability of hard cover also helps to offset the poor armour of the SUM, although its poor reverse speed is a distinct drawback. In more open maps, the SUM is very dependent on concealment using trees and bushes, as the armour is generally not reliable and the open crew compartment makes it a very common target for aircraft strafing runs if it is spotted.
Not only does it not have a rotating turret, it has an open top and practically no protection from behind. Therefore, when an engagement's complexity evolves and the Su is surrounded, there is little that can be done to survive. One well placed hit to its rear will knock out a good part of the exposed crew, even machine guns can do the job of eliminating both loader and gunner.
It is crucial to remain at a distance from the enemy, perhaps even seek the cover of trees for protection against low-level attack aircraft, and to only ever give the front side to an enemy. The fact that this vehicle does not have a turret not only means that it is not effective when fighting more mobile enemies attempting to flank, it also means that placing the armour at an angle is not a viable strategy to increase relative armour thickness and stay more protected, since the gun's limits for horizontal traverse mean that any significant angle of the hull towards an enemy will make make it harder to keep the enemy in sight.
What can be done is to fire a shot and, immediately after, angle the hull whilst reloading , to then return to facing the enemy to fire another shot. However, hiding whilst reloading is the most sensible choice.
Unfortunately, the SU has low mobility, handling, and a vastly different gun when compared to its smaller and more mobile cousin, the ZiS However, the gun on the SU is definitely more powerful than the ZiS's 57 mm. The sheer force of the 76 mm shells will cause huge amounts of trauma to a target upon penetration. The SU is also more well armoured than the ZiS and provides much more protection to the gunner crew, especially from smaller caliber rounds Unless fired from the rear.
Given its poor gun depression and velocity, the SU should be used as a mobile brawler and ambusher. It is well suited to performing ambushes in urban areas. The high HE filler of the 76 mm shell makes it capable of knocking out nearly all enemy armour at its BR with a single shot. A minor issue with the SU is that it has no defensive machine gun, meaning that responding quickly to SPAA is difficult.
The gun in itself is what makes the SUM a good vehicle, all its other characteristics are less than impressive. It features noticeably more penetration and a better fuze in exchange for somewhat less explosive mass. Despite this, the SUM will often destroy most enemies in one shot when the shells penetrate.
Once unlocked, the SU is quite capable of dealing with any tank it is likely to see from the front, though there may be a need to swap ammunition often to deal with different targets.
M4A3 : This low-rank Sherman posts a huge threat to every of its opponents due to its superior armour and destructive firepower. Its armour is overall quite tough to penetrate with your short 76 mm gun, but it can be solved by careful aiming. If the M4 is within m, use default APHE to shoot at the vertical part of its gun mantlet or its side if exposed.
When the M4 is further than m away, all of your shells will perform poorly at penetrating its armour, so disengage or wait until it gets closer. During the interwar years, the development of self-propelled artillery was practically nonexistent in the Soviet Union.
The situation changed after the German invasion in , and vehicles such as the SU or SU , based on the KV-1 and T tanks respectively, were developed. In November , the State Defense Committee then ordered the production of a light self-propelled gun, built on the chassis of a light tank and armed with a The T light tank chassis was chosen, as the other light tanks, the T and T , was already out of production.
The chassis had to be modified for this role, so it was lengthened and had one additional pair of road wheels added to the design. The armament, the The gun was positioned at the rear, with the transmission being mounted frontally. However, after only a couple of hundred vehicles were produced, the production was halted due to serious mechanical problems and other issues.
The power train consisted of two GAZ automobile engines, with each powering one track. However, there was no synchronization gear, so the driver has to control both engines simultaneously, which was an extremely difficult task. This arrangement also caused strong vibrations, which were the cause of frequent engine and transmission failures. The second biggest issue was the enclosed crew compartment, as it was very cramped and offered only a little space for crew members to work properly.
The vehicle thus had to be modified, firstly the roof of the crew compartment was removed, improving the access to the gun. The power train was also changed, receiving the more powerful GAZ engines, each producing 85 horsepower, which was now mounted in tandem on the right side of the vehicle, propelling a single drive-shaft.
The modified vehicle was designated SUM , and its production was resumed in early More than 14, SUM's were produced between , making it the second most produced armoured vehicle in the Soviet Union after the T tank.
In its intended role, the SUM replaced earlier infantry support tanks and was very welcome to Soviet infantry units as it provided them with a light and mobile universal support weapon. The vehicle was meant to be part of three battlefield roles - a light assault gun, a mobile tank destroyer, or a mobile artillery gun as the weapon could be fired indirectly at a range of 17 km. The vehicle was fairly lightweight and produced low ground pressure, enabling it to pass through terrain unsuitable for heavier vehicles.
Its gun could utilize a multitude of ammunition types, aside from standard high explosive ammunition, it could use fragmentation, shrapnel, incendiary and smoke rounds. The introduction of the APCR and HEAT rounds then enabled SUM units to engage even heavier Panther and Tiger tanks with some success, though crew manuals instructed the gunner to try to hit the tracks or gun barrels before these rounds were made.
The SUM assault gun is a somewhat inexpensive assault gun that can take on infantry as well as anti-tank units. But unfortunately, due to the weakness of the SUM, neither goal is usually accomplished when it's attacking head-on. The SUM fires a damage dealing shell. Couple penetration value 93 , turning this gun into a subpar weapon against most tanks, though it enjoys a fairly good rate of fire.
It's useful when attacking with suprise using the True Sight system to the users advantage, with a nice firing range of Used correctly, it poses a good threat to enemy armor, even heavy tanks.
Next, the unit also has a barrage ability, identical to the barrage ability of the ZiS-3 AT gun. This ability is free however, unlike the ZiS-3 AT gun which costs 60 Upon activating, the SUM will fire a salvo of HE-shells on the targeted location, dealing reliable damage.
This is indeed a very useful ability, but with a long cooldown timer. This means that the SUM will have a poor self-defense against enemy infantry after firing the barrage, if not supported by friendly infantry. Despite having some armor, enough to stop small arms fire the health makes the unit vulnerable roughly just as fragile as a light tank : at least 3 hits from Panzerschrecks will destroy it.
Also, Grenadiers and Volksgrenadiers can cripple this unit with one Panzerfaust, leaving it easy prey for other Anti-Tank units. Medium tanks also do not have to worry much about this unit, as shots will often finish it off. Also watch out for enemy assault guns such as the Stug III and the Jagdpanzer as these have comparable range but stronger armor. Then look at the penetration, damage, accuracy, RoF, and aim time values.
Penetration is genearlly the most favored stat due to its ability to deliver reliable and consistent damage on higher tier tanks, but be sure to check the rest of the stats to ensure you are not gimping yourself.
For the SU, go with the tier six 57mm ZiS-2 cannon for its higher penetration for more reliable damage , RoF, accuracy, and aim time than the 76mm ZiS-3 cannon. Enaris 4 Posted Jul 15 - Major. If you want to make the SU a long term vehicle, the ZiS-2 is an awesome gun. It's fast, super accurate and has very good pen. In fact, it can pen anything you'd meet in a typical fight Though KV and T-1's may give you issues depending on the angle to them.
You can punch the front armor, but not if it's at an off angle. The only real downside is the lack of damage, which can be a real problem at times, but it's incredibly well suited for sniping, and with a bit of practice, you can begin to use that awesome rate of fire to make up for the lack of damage on any given shot. Rypper 5 Posted Jul 15 - Major. Definitely ZiS Great gun.
