It would seem the skill explanation is only related to RB. Should we add RB/AB differentiation? If so, should certain skills be highlighted more, as of their importance in certain modes is astronomically higher? (Radio communication is broken OP in AB for certain classes of tanks.)
EX: Radio communication: AB: Automatically shows player any enemy in certain range around them on minimap, if any allied vehicle (including aircrafts) sees them. RB: increases the range at which the enemy players detected by the allied team are displayed (through red arrows pointing downward). Skill effect can be increased by up to 100%.
Some skills could be also further explained, but that would clutter the "list" a bit.
