Armor科技（基础版）

For armor technology with 一步不退, see 装甲科技.

装甲科技 unlocks different models of armored vehicles, including tanks and armor variants like self-propelled anti-air, self-propelled artillery, and tank destroyers. Thanks to their high breakthrough, tanks can act as armed and armored offensive specialists, while armor variants can act as more heavily armed and armored versions of motorized combat support units. These vehicles are also split into light, medium, heavy, super-heavy versions, and amphibious versions). Light tanks and their variants tend to be fast, inexpensive, but weak, medium tanks and their variants tend to be the most cost-effective but still slower and more expensive than light tanks, and heavy tanks and their variants tend to be the most combat-capable but also by far the most expensive and the ones with the most difficulty with adverse terrain. Super-heavy tanks and their variants are even slower, even more expensive, and even worse in adverse terrain than heavy tanks and can only be used in smaller numbers as 支援连, but when they can be effectively fielded, they can be incredibly powerful.

随着《诸神黄昏》引入特殊项目以及随之而来的补丁 1.15，所有装甲科技现在在研究时也会产生陆战突破进度。装甲科技还与陆地巡洋舰陆战特殊项目特别紧密交织。

Armor Variants

All tank models (except for amphibious ones) have three armor variants that can be unlocked through individual technologies: 坦克歼击车, 自行火炮, and 自行防空炮. The buttons for each of these can be found next to their corresponding tank model technology.

Switching production from the base model to a variant results in a much lower loss of production efficiency than usual; it can be useful to co-opt an obsolete tank line into producing variants rather than upgraded tanks. This represents the historical practice of repurposing obsolete tanks into specialized variants, which was much cheaper and quicker than simply scrapping them. Light, medium, heavy, super-heavy and modern variants each have their own battalion types and will not request equipment from other lines. Some variants also use less equipment than their corresponding tank battalions.

坦克歼击车

坦克歼击车, also known as TDs, are dedicated, armored anti-tank vehicles. They are essentially an anti-tank gun on a tank chassis. Tank destroyer battalions can be thought of as the armored equivalent of 摩托化反坦克 battalions. Historically, most tank destroyers had a casemate with a narrow range of travel for the gun instead of a turret, and many early models were open-topped.

Tank destroyers generally trade higher piercing and hard attack for lower soft attack, lower organization, and far lower breakthrough. Since 40%^[1] of a division's piercing and 40%^[2] of its armor comes from the battalions in the division with the highest values for those, even just a single tank destroyer battalion can significantly boost the combat-effectiveness of an entire division and reduce its need for unarmored anti-tank battalions or 支援连.

自行火炮

自行火炮, also known as self-propelled guns or SPGs, are essentially artillery guns on tank chassis. They can be thought of as the armored equivalent of 摩托化火炮. Historically, most self-propelled artillery had a fixed gun mounting with limited horizontal travel instead of a turret, and many early models were open-topped.

Self-propelled artillery generally trade higher soft attack for lower hard attack, lower piercing, lower hardness, lower armor, lower organization, and far lower breakthrough. However, they are still more heavily armored than their truck-drawn counterparts. Since 40%^[2] of a division's armor comes from the battalion in the division with the highest armor, they can be particularly useful as an armored complement to divisions that otherwise would have used an unarmored artillery piece for its soft attack.

自行防空炮

自行防空炮, also known as SPAA, are dedicated anti-air guns mounted on tank chassis. They can be thought of as the armored equivalent of 摩托化防空. Historically, dedicated armored vehicles carrying anti-air guns came late in the war, the earliest example being the Hungarian 40M Nimród in 1943. Most anti-air vehicles were mounted on trucks instead, making them more like 摩托化防空.

Self-propelled anti-air gain air attack at the expense of slightly higher production cost, lower soft attack, lower hard attack, lower piercing, lower hardness, lower armor, lower organization, and far lower breakthrough. While this may seem like a huge sacrifice for something so minor, SPAA are still relatively fast and armored and still have enough piercing to pierce lighter, obsolete armor and Mechanized infantry. Since 40%^[2] of a division's armor comes from the battalion in the division with the highest armor, they can be particularly useful as an armored complement to divisions that would want some anti-air capabilities anyway and would otherwise be completely unarmored.
