Big Brother Mentor: Lupon Kravshera is this to his subordinate officers. Avital is a Big Sister Mentor to the enlistees under Jack's command, and the enlistees of the battalion as a whole after her promotion to master sergeant.
Tomas Cabon was this to the enlistees of the battalion until he was killed in combat.
Character Development: The protagonist gets this, as his experiences in the war clearly changed him. Those changes were noticeable when he came home to Jamaica for Christmas vacation.
Jack Emerson gets this too, as he was simply an officer who was initially Only in It for the Money while wanting to be a rap star, and later developed as a leader, especially after he took command of the battalion when Lupon Kravshera was injured.
Also the successors of the Ruling Triumvirate of the Robotech Masters, who are known only by the color of the dresses that they wear.
Number Two: Jack, to Kravshera, after his promotion to major.
Mike was this to Jack until Jack's promotion.
Related to the sub note above, the protagonist is this to Mike after Jack is promoted.
Original Character: the fic focuses on original characters, though they meet the canon characters at various points in the story.
Only in It for the Money: most of the servicemen in the United Earth Forces fit this trope. This is plainly demonstrated when after their paychecks bounce due to corrupt officials looting the World Bank and the International Monetary Fund, most of them desert.
Jack was this, initially.
Put on a Bus: This happens to Melissa Sharp when she is transferred to Tirol after the protagonist is captured by the Robotech Masters.
Mike boards the bus when he deserts after his paycheck bounces.
The protagonist himself is put on a bus when he is captured by the Robotech Masters during their attack on Casablanca.
Senseless Sacrifice: Supreme Commander Leonard sends a massive attack force against the Robotech Masters, which fails spectacularly. Nina was among those who were killed.
One of the main characters, Jack, is the son of General Rolf Emerson. In Super Dimensional Cavalry Southern Cross the son of Emerson's counterpart was Bowie's counterpart.
the protagonist/narrator is unnamed, just like the protagonist/narrator in Scoop
Lupon Kravshera's surname and physical description is taken from Quamzin Kravshera, an antagonist from Super Dimensional Fortress Macross.
Glenn La Belle is the same person who had been born on the SDF-1 in Scoop
In the story, he gets married, and happens to share a surname with a certain New Generation character who would have been born around the time of the Robotech Masters saga. Coincidence?
After the mission to infiltrate an enemy mothership, the ship U.E.S. Henry J. Gloval picked up the protagonist and some of the other soldiers after they were rescued after they were sucked out into space.
Isamu Shirogane was named after two of the pilots in Beast King Golion. He suffers the fate of his last namesake.
The Robotech Masters capture Earth residents and use them to pilot bioroids. The same thing happened with the Zor using captured Glorie citizens in their mecha.
Space Is Noisy: Averted when the protagonist is sucked out of an enemy mothership he infiltrated after an explosion breached the hull.
Justified whenever the protagonist rides in a transport ship, as the rocket engines are noisy, and anything that hits the ship (and does not destroy it) would generate sound within the ship.
Spanner in the Works: After the war, the United Nations made a deal with the Robotech Masters, now under new leadership, to rebuild the Earth and prepare for the Invid invasion. But the new U.N. Secretary General and some Corrupt Bureaucrats loot the World Bank and the International Monetary Fund, thus depriving the world of the money needed for reconstruction, and providing incentive for many UEF servicemen to desert. Furthermore, the member nation-states fail to send enough delegates to reconvene the General Assembly, further hampering Earth's preparation for the Invid invasion.
