I had an idea for a challenge. A banner of Stars or crest of Stars / Halo crossover. Since I can't find much mention about Earth other than it name being mentioned a few times a drink toast to Earth. So it sounds a bit like Earth's a distant legend. Well here's the thought why not sometime during the war between the Abh and the Four Nations Alliance of humankind. Then due to unforeseen events on a far boarder between the two powers a UNSC ship shows up and starts scans and leaves. The few ships in the area of both sides start going in an up roar with the unknown ship showing up in areas so far away from the fighting and leaving quickly. Then later some events can follow and the UNSC soon finds itself at war with both the Abh and the Four Nations Alliance of humankind. The UNSC may not has as large fleets as both Abh and the Alliance but the UNSC's ships have many advantages. Like the fact they use space FTL that doesn't involve plainspace. That means their ships can go from one place to another without anyone noticing and can be surprised attacked at any time. (the reverse is somewhat true though but with the UNSC only using Real space it forces both sides to fight in real space more than they normally do) The UNSC also has a massive range advantage. The MAC guns coupled with AI targeting can seriously take out ships. In fact looking at the armament level of them and the fact the Abh consider nuclear weapons to be primitive....well I wonder if they would change their tune after being on the receiving end of a Shiva. It's odd that the Abh seem to have this personality that their technology and computer systems are perfect or something (no manual checking even UNSC ships have that and they have AI's). Another large advantage is either side has anything like space fighters. The UNSC can cause massive damage to the enemy with their unique fighter support, cover, and attacks.
