What can a mechanical repairman do? Research, modification, and ingenious ideas? What can a mecha warrior do? Mecha combat, skillful operation, and unique fighting styles? What can a special reconnaissance soldier do? Go deep behind enemy lines, engage in hand-to-hand combat, defeat the enemy with one move, disguise, stealth, and snipe? What can a military staff officer do? War situation deduction, action planning, and winning with surprise? A genius who combines three professions and is even proficient in psychology, deception, and assassin disguise techniques, is actually cowardly, despicable, and inferior.
