From the beginning of the Legend of Korra, the show has shown the positive effects of technology and the negative effects of technology. We have seen how whimsical they can be and the drive behind why they are created.
Lets start with this.....
As we know, in the episode "The Battle for Zaofu", we all saw what the power of the spirit weapons possessed. Originally, the spirit vines were to be used to make clean energy power for the "Earth Empire". Varrick tried his best to destroy all traces of his work when he destroyed the train with all of the materials in it, but unfortunately Baatar Jr. watched and observed everything Varrick was doing when he was building the bomb, and replicated his work into what seemed to be a cannon at the time in the episode "Operation BeiFong".
Zhu Li tried her best to completely destroy the weapon by sabotaging small pieces to the weapon. Zhu Li will go down in history for trying her best, but it did not work.
At the end of "Operation Beifong", Zhu Li reveals that Kuvira is planning to attack Republic City in 2 weeks. But by now, you should expect to never rest your thoughts on that.
The basic definition of "Gambit" is to "Sacrifice something (or someone) to gain a advantage". We already knew in the beginning that Kuvira would have to sacrifice something. We know that there are only 2 things close to Kuvira's heart is the Earth Empire and Baatar Jr. I doubt that Kuvira would sacrifice the Earth Empire after working to "reunite" it for 3 years. The logical choice would be, She will sacrifice Baatar Jr. to finish her conquest to fully unite the Earth Empire by claiming Republic City.
As soon as Zhu Li told President Raiko that Kuvira would be attacking in "2 weeks", Team Avatar and everyone, even Pema helped Wu by evacuating all citizens of Republic City.
Asami and Varrick start pushing the production of their flying mecha-suits. Lin, Mako, and Prince Wu have the task of getting the people to flee the city. Mako caused confusion but surprisingly Wu saves the day.
Korra, Mako, Bolin, and Asami decide to take out the mega weapon to make it easier for the Republic Army to fight Kuvira's forces. Little did they know that it was a 20 story mecha suit!
