Chương 549: Prepare for a war on May 12th.

Nowadays, the tank production factories of the Great Tang Group, including those on Dragon Island and in Tongcheng, are only producing two types of tank chassis. One is the chassis of the Number 4 tank, and the other is that of the Number 2 tank.

The chassis of the Number 4 tank is basically all used to manufacture the Number 4 tank itself, as the military urgently needs this new type of tank to fill vacancies, leaving no surplus production.

Production of the Number 2 tank's chassis continues, primarily for conversion into self-propelled artillery to equip the troops.

The Great Tang Kingdom was the first country in the world to equip its forces with self-propelled howitzers, starting with a 105mm caliber, which was quite advanced technologically.

It was because of this new type of artillery that the Great Tang Kingdom's armored corps could guarantee sufficient artillery support for their ground forces during rapid advances.
