While Military Appreciation Month is usually just recognized in the US, we like the idea of honoring current and former men and women in service, especially considering that we are also celebrating the 75th anniversary of Victory in Europe Day this year. On 8 May 1945, the Allies accepted the unconditional surrender of Nazi Germany, marking the end of World War II in Europe.

Why are they offering the M4 Improved almost every month? Everybody knows it’s garbage.
For players like yourself perhaps.
It’s a trap for the newbies… You chose the M4 improved? Better luck next time!
Anybody knows what you get if you have the selected premium tank already? Like i have the AT 15 A, so do i get the gold value if i chose it again?
I like these rewards, wanted to buy Pudel anyway so this one came rly handy.
what I don’t get: They offer three tanks as last reward. one tier 7 TD (that is not really good even after the buffs), a pretty decent tier 6 med (that I hope will one get the same treatment like the Rudy) and a rather garbage tier 5 med.
if you had to pay money for them, the difference would be big, but here you have the same effort (well, play one game a day …) for each of them.
WG logic at its best, I guess …
