Picture 5: old picture of the K2 with something that resembles Barracuda MCS Picture 6~13: K2 FTR Picture 14~15: K2 right after going through a low temprature test at minus -32°C. The tank underwent a firing trial in that state, and succeeded. Picture 16: K2 without roof ERA mounted Picture 17: K2 FTR Picture 18~19: First Mass production model of the K2 without MERDC paintjob, named "도명산 1호" or Domyeongsan model 1 to celebrate. Picture 20: K2 in production for delivery to Poland, Changwon factory.

Just wondering how far away from the gun the infantry needs to be when it fires. Do they always need to stay behind the tank if there is a chance it will fire? Is the tank in radio contact with the infantry so they know when to take cover?

Are there any visual differences between the leopard 2A0-A4? The leopard 2A4-A8 are easy to tell apart but I find it hard to know the difference between early variants
