Alright, so I unlocked all rewards available, and after a time of playing with them, I had decided to rank them based on practicality.
- Sword Selection(I had chosen the German toothpick)
It’s fun to run around for a moment, but then you just get moved down by Soviet SMGS. 2/10
3.Soviet SMG Squad and the SMG itself
It’s alright, but it doesn’t beat the 71 drum mag on PPSH. I had some fun but ran out of ammo like crazy. Switch to the semi to conserve ammo, but let’s be honest, its an SMG. The Squad is meh, not great, not terrible. (I believe that people have their own opinions) 4.5/10
2.FW-189
I had to grind to level 7 to play it in the Moscow campaign, but bombs are working as intended, and it can stand its ground. If you are interested in taking scenic pictures, the visibility from the cockpit is perfect. I wish there was a rewarding spotting feature or an artillery option, as this aircraft is a spotter and army corporation aircraft. 7/10
1.M5A1 Rhino
Probably the best reward to come out of this Battle Summer event. I had become a demolitionist, farmer, gardener, and Vlad the Impaler. On the side, I drift around the tank hedgehogs on the beach or race around the church with Pumas. 
Improved shells are good, but the explosive filler is nowhere to be seen(Maybe they didn’t have them, don’t know for sure). 9/10
Final Thoughts and Suggestion
The format is good, but it allow us to choose the missions or complete them simultaneously.
Yes, there is an incentive just to buy the mission, but I believe that devs and whoever designed these missions can do better as this is the game with great potential and has a loyal community, which wants to see this IP do better. I pretty much stopped playing War Thunder because of this, because I see the potential.
Give Germans in Berlin, a few more vehicle squads; it’s getting tired of grinding on the Panzer 4 J.
I still wish for the customization of the tanks, but it’s still an Open Beta.
