Captain John 1: A Galactic Coming of Age

Read Captain John 1: A Galactic Coming of Age Storyline:

Normally Federation members are not allowed to contact developing races. Races operating within their own planetary systems are to be left alone until they begin to develop the ability to travel at FTL (faster than light speeds).
When the ability to travel at FTL becomes apparent, one of the members of the Federation is nominated to help ease the newcomer through the Galactic citizenship process.
Unfortunately, not all the galaxies systems belong to the Federation, and some of those systems are much less than friendly. The last several decades have seen the development of war like societies that systematically loot developing planets. They take the water, and other precious resources, including slaves, leaving the remaining native inhabitants a barren planet. Without resources the population simply dies a slow death.
The Egolari are here because we, meaning the people of Earth, happen to possess a skill set and an aptitude that is critical to the needs of the Federation.
The major problem within the Federation is that virtually all the members have, for centuries been living in peace. They have developed a society that is not well suited to counter the growing violence presented by the nonaligned races. In short, they have no way to protect themselves, let alone protect the fledgling races just arriving on the galactic scene.
Enter Earth. Of all the emerging races to become future galactic members, one has a superior potential to face the violence threatened by the nonaligned races. You guessed it, Humanity.
The Federation realized that to continue to function as an organized galactic society, they would have to develop a military arm that could provide the Federation and emerging systems the protection of a fleet of space vessels and marines. Humanity was the race most capable of leading the development of that military organization because we had not progressed so far that our war like tendencies had begun to erode.
Although we were not yet ready for galactic membership, we were a necessity that could fill the need, thus we were getting a crash course in how to travel the galaxy, protecting ourselves and the Federation with the full expectation that we would go where no human has gone before, and kick some alien ass.
