Trivia

 * Strangely, this tank is the same tier as the AGM-114, a homing Rocketeer.
 * Even more strangely, the changelogs described Cosmonaut as a Rocketeer when it was initially added.
 * At one point, this tank was decreased to level 45 and AGM-114 branched directly from it, resolving this curiosity.
 * Despite not being rapid-fire or having smaller missiles, the reason Cosmonaut may branch from Molotov may relate to both words' shared Russian origin.
