War is no place for a man. The civil war on Pental V is a perfect example of why men should let the fighting be done by those who know best how: women. Modern weapons make men obsolete on the battlefield.
Earth wanted to earn their keep in the Community of Worlds so they offered to send a small peacekeeping force to Pental. Nobody thought humans would be dumb enough to send men to do the fighting. When the troops and advisers arrived they insisted they were the best Earth had to offer.
On the battlefield the men advanced as they were trained. One massive burst of girly light fire and the men were all gone; they were women now. Disoriented, the girls were captured and brought to the enemy training camp. The new girls were trained to fight like women, the only real warriors.
Ricky was the best man in the peacekeeping force from Earth. Now she is the best woman soldier fighting for the rebels. They call her Sarah now. She has a way of tricking the enemy into vulnerable positions and then cutting them down.
Earth is still trying to find their place in the Community of Worlds. But what can you expect from a primitive world? Humans will do fine; it should take no more than 70-80% of the men being turned into girls to get the job done.
