Researching the second tank in a folder first

Hello all! I’ve got a question regarding research. I took a hiatus from playing WT for some time and when I returned, the tech tree was shuffled. I have about half of the RP needed to research the M48A1, the second vehicle in this folder. Will I be able to purchase this tank upon completion? Or, will I need to research the M46 first, before being able to purchase the M48A1?

You will have to research and buy first vehicle afaik

Yeah… no shortcuts here I’m afraid. You’ll have to still research and buy the first tank.

Whow, they got cheap now!
