Siyuan and they have roughly decided that they want to buy tank destroyers.

Siyuan took two tank destroyers on a test drive.

Siyuan's roommate also observed the various characteristics of the two on the side.

Siyuan: They found some characteristics in depth.

About this Tannifer with a small turret of 37 guns.

This 85mm gun has some armor-piercing shells from the hood as a backup, and grenades can also be selected.

Among them, the armor-piercing bullet from the hood is a kinetic energy bullet, and its armor-piercing ability decreases as the attack distance increases.

Let's take a look at the Tan Zhan with its 122mm howitzer.

For this tank, the 122mm howitzer was equipped with grenades, armor-piercing shells and smoke grenades.

Needless to say, the grenade has a weaker armor-piercing effect and a stronger explosive effect.

In the case of armor-piercing shells, the armor of the opposing land unit is pierced by the metal jet created when the shell explodes.

Therefore, whether it is at a distance of 300 meters, or a distance of 1,000 meters, or even a distance of 2,000 meters, if it hits, the penetration depth of the armor-piercing projectile will be the same when the angle of incidence is fixed.

In addition, when Siyuan was test driving, they also found another feature of these two cars - the Tan Zhan equipped with an 85 mm gun, the trajectory of its main gun is relatively straight, and the trajectory of the other Tan Zhan 122 mm howitzer is slightly curved.

The ballistic trajectory is straight and curved, and either of the two is actually not a complete advantage or disadvantage, each with its own advantages and disadvantages.

Needless to say, the advantage of a straight trajectory is that it is easy to aim and it is easier to hit accurately.

And the ballistic curve is not useless - at a long distance, the curved trajectory can under certain circumstances allow the tank to attack ground targets hiding behind low obstacles.

The reload time is also one of the considerations, the reload time of the 85 gun is less than the reload time of the 122 grenade break.

"I think so!" Siyuan said, "The 122 howitzer's annihilation may be more suitable for me." ”

"Well, how do you say that?" Hongkai asked from the side.

"That's right." Siyuan explained, "Considering the characteristics of the command vehicle, the command vehicle will generally command or fight at a distance from the front line of operations, so I need to have armor fragmentation bullets to ensure long-range attack power!" As for the reload time, I was driving a command vehicle, and I personally felt that there should be no need for a high reload speed. That 122 howitzer tannihilation,"

"Well, that makes sense!" Hongkai nodded and agreed.

"Okay! So...... Purchase! Tick the box to use the coupon! Siyuan said as he clicked the mouse and proceeded with the purchase steps.

Soon, the purchase was complete.

Siyuan admired the new car he bought with great interest, as if he was playing with a literary toy.

"Perhaps, I'll have to buy a plant disguise!" Siyuan thought about it while looking at the newly bought Tan An.

"You said the camouflage plant that you bought with gold coins."

Before Hanyin finished speaking, Siyuan happily opened the mobile phone payment tool: "Krypton Krypton Gold!" If you switch to land warfare, you can be fully prepared! ”
