The Great War ends and Tanya finds herself on the losing side. Instead of staying to face war crimes trials and kangaroo courts for herself and her men over carrying out perfectly legal and legitimate tactics against the enemy, she decides to retreat advance in another direction to Brazil Brasa, where she will have to start over nearly from scratch to build up and prepare for a coming Second Great War. Things get... complicated from there. A Youjo Senki continuation with Metal Gear and Tom Clancy themes and elements (not a crossover).
