The insectoid Gorram Empire is conducting a planetary assault of Earth. The Gorram have 10 tokens that represent their massive invasion fleet and armored walkers with fiery death rays. Earth has all the world's militaries at their disposal. Given the superiority of Gorram technology and greater numbers, the GM decides the Earth Defense Force (EDF) gets 8 tokens.
Both sides have heavy artillery and air support (+3 to both sides), but there are no terrain advantages since it's a world-wide battle.
The Gorram Empire makes a Knowledge (Battle) roll and gets a 13. The player characters load up in stratospheric fighters and lend a hand. Collectively, they suffer some damage but also add a grand total of +3 to the roll. The EDF's Knowledge (Battle) final total is 17–Earth wins by 4. That destroys two of the invaders' tokens and 20% of their force.
The Game Master describes the first few hours of the invasion and a spirited defense by earth's militaries. The evil insectoids are dealt heavy losses, but are far from defeated, and the battle goes on.
