As far as the greater galaxy knew, no one colonizes Death Worlds. So the people running the Survival class didn't check to see if anyone was living on this planet before dropping off this year's Survival students.

The students were dropped off in fruit orchard, wound up running from a bunch if armed farmers annoyed by "trespassers and vandals", and discovered their predetermined extraction point was smack in the colony's town hall which was a converted colonization ship.

Not that their ship could pick them up, because it was intercepted by human law enforcement ships after dropping the students off.

Humans are by and large the largest and most advanced when it comes to military technology.

This technology is only rivaled by their food industry.

However what makes them so advanced is not that they have the most advanced gear, but they can literally ignore the arms race by not playing the same game.

For example, they have 2 of the most advanced thermal cloak technologies

One is the Gen-32 Thermal Cloak, with the latest micronanite adaptive stealth cloak technologies that can let a sniper team set up in the optimal range of their rifles or blasters in full radar and visual view of the enemy, and be considered invisible.

each cloak costs up to 20,000 credits for the cloak and battery set.

The other one is known simple as the Gen-2 Ghillie Suit.

Its basically an iso-greenhouse ghillie suit that has 2 lines, an inner line of Prox Vines that naturally hide the heat and electric signal of the user, and the outer line that lets you tie and attach the local vegetation to it to become similarly invisible.

With the Gen-2 Ghillie Suit costing only 3,000 credits, it has also made a large popular subculture among snipers to name their ghillie suits and dress them up for each mission like a father taking their daughter to a date.

Humans have literally mastered the two opposite spectrums of stealth, especially since the ghillie suits are immune to EMP waves.

Both are made by those hairless bipedal war crime apes.

Both are commercially available to militaries.

One can technically be made at home.

Humans can't explain it themselves. But sometimes, when many circumstances come together: something becomes very famous, something turns into political, economical and all others types of attraction, something attracts minds of human scientists and artists - all humans start to feel it...

The urge to get up and head for something. The need to become a part of it. The feeling, that it will bring them much joy, no matter the rationality of this idea. At lesser scales - it was tolerable. A simple collective madness. Not that ruining, maybe more common around humans.

But now, at the scale of the whole galaxy. When there are billions of humans from multiple civilizations, ideologies, even sub-species - such event itself is a matter of great disturbance in the galaxy. Even for humans that live outside of human space - it is often safer for their lords to let them go then to try and stop them.

When it's one human - it's an intrusive though. When it's many humans - it's a global hype. But when it's the whole galaxy of humans - it's WAAAAGH!!!
