Space is a dangerous place. Here you are either a predator or a victim that neighbors will quickly eat. And if your teeth are not sharp enough, there must be a force behind you that can protect you from other predators. Previously, such a force guarding the Earth was the great gekho race. But the gekho fell under the onslaught of enemies, and now the Earth must defend itself. And it is better to immediately show everyone in space that jokes are bad with Earth's humanity, since our planet has not only a powerful Earth Army and its own cosmoflot, but also something unique that no other race has. Earth has a Mosquito and its ancient cruiser instantly moving around the Universe, breaking all the usual frames and laws of war.
