Holiday Ops 2023 through January 9, 2023 at 07:00 CET (UTC+1)
If you haven’t done yet you can use discounts to make some credits, once you complete the Holiday Ops Challenge missions. The best-suited tanks to buy at a discount, and sell afterward, are as follows (the list did not change since last year)
• M14 / 41 (Italy, MT-2): 2050 credits profit
• M15 / 42 (Italy, MT-3): 22700 credits profit
• B1 (France, HT-4): 92500 credits profit
• T1 Heavy Tank (USA, HT-5): 130500 credits profit.
• O-I or Hellcat (Japan, HT-6 / USA, TD-6): 95000 credits profit.
The total maximum possible profit is 342750 credits.
Too late for me, didn’t buy any of those just to sell them later.
