From 3.3br to 6.0, the Germans had a whole set of air defense systems, such as Sd.Kfz.251/21, Ostwind, Wirbelwind, Zerst ö rer 45, etc
Since t77e1 and Skink joined the game, the United States has also had a good air defense system in 4.0-6.0br
Compared with the above two, the USSR is undoubtedly tragic. Since BTRZD went to 6.0, the Soviet Union did not have any anti air vehicles in 4.3-5.7, and could only use BTR152D. However, in 5.3-5.7, BTR152D was already weak
What? USSR has enough SPAA to adequately cover off every BR. The BTR-152D has 4x 14.5mm which more than fill the gap between 4.0 and 5.7.
Have you actually played some of the other nations? Britain? They have the Bosvark and Skink at 5.3 which has to carry them through to 8.3 where Gaijin being Gaijin grouped 3x SPAAs at 8.3.
Japan has the Sub-I-II at 5.3 which again has to carry them through until 8.3.
BTR-152D in my honest opinion is same efficient against ground and air targets, the 14.5 mm HMG are very effective and deals good damage against aircraft and can be effective side on against some of the most commons vehicles you can face at its battle rating and few at battle rating 5.7 range.
BTR152D and goddamn twin 25mm milk truck are both netter than Ostwind II anyway as 2 14,5mm HE bullets will wreck a plane most of the time and they have plenty of range. Milktruck one-shots fighter planes.
Other small countries do not need to take on the majority of offensive and defensive responsibilities like the United States, Soviet Union, and Germany. Secondly, the United States, Soviet Union, and Germany have the highest number of players
