Oh man this tier 4 French Premium Artillery is more fun than I thought it would be!
I also picked up the Ram 2 today. It's the missing link between the Lee, which I love, and the M4, which I have. It also has 5 crew slots, so it can train US medium crews up to tier ten.
This sale is going well for me spending money. I got a bunch of equipment, two premium tanks, more barracks bunks (not on sale), and some more garage spaces.
