The armored vehicles and gun carriers that were manufactured and fielded by Czechoslovakia during the annexation by Germany in WW2 and cold war era. They have good firepower and are quite fast but sacrifice protection and durability.
Czech Light Tanks are slower than light tanks of all nations except the early light vehicles on the French Tech Tree. However, these tanks sport decent armor and all around good firepower.
Czech Medium Tanks are very fast, with little armor, but good guns. Three of these, the Škoda T 25, the Škoda T 50, and the TVP T 50/51, have autoloader cannons, which provide for good DPM. In the beginning, the mediums are identical to the light tanks in playstyle (supporting role), but from Tier 5 and upwards, the tanks can function as scouts and can easily flank an unaware enemy assault. These tanks also function as excellent snipers due to accurate guns, decent penetration, and good camouflage values. In fact, mediums on or above tier 6, excluding the Konštrukta T-34/100, play like the British tier 6 medium, the Cromwell. A major problem with all Czech tanks of Tier 5 and higher is the weak stock suspension, which has to be upgraded before any other upgrades can be mounted. This makes for rather painful grinds. Another issue is the vulnerability of the ammunition storage, which makes the choice of a modified configuration viable.
With the addition of the new Czech heavies, they fill a support or breakthrough role with the choice of guns with 1 or 2 shell capacity. They have decent armor, mobility, and firepower but like the mediums in their tier, painful stock gun and suspension grinds.
