How much iron from sergeant 3 to general?

Hello,

Not really played tour of duty season 2 to be honest. I like Baird though but seen I need Lieutenant Colonel 3 for gilded Baird :). I see there’s like a week to go, how much iron would I need to spend to do daily challenges roughly to get to lieutenant colonel and how much should I spend each day to be as cheap and efficient as possible lol? Any help with the maths appreciated!

Depends tbh,

When I re-roll,

I only look for 2-3 star MP challenges as I’m not playing anything else.

It’s all random tbh.

The medals are worth going for anyway if you haven’t already.

Would really need to be sure you want to waste money on a skin like that or just save your money for the Op3 bundle (sure there will be one).
