In 2018, the social media account of a guerrilla group in a certain country posted some daily photos of the army. The heavily modified Pz.lll VK3.07A 3 in the photo is particularly eye-catching. Under the sandy paint, the new heavy external armor, explosive reaction armor, active defense system, and anti-tank missile are installed on this 58-year-old "old car." The main gun was also removed and replaced with a 120mm smoothbore gun. This series of modifications not only gave this mechanical giant born in the early Cold War a new life and vitality, but also concealed the use of old equipment and local battlefield wisdom.
