The old model was REX, the new improved model RAY, then there was JACK. But you can’t use virtual data on a battlefield…
In MGS1 Otacon told Snake that the Shadow Moses incident happened when they were going to test Rex. [He explained that they had developed a new kind of nuclear weapon in a VR testing lab. The problem being that you can’t use virtual data on a battlefield. You would need actual launch data.](https://youtu.be/b3IPlKiRXTs?is=VBnS_36TS4GHz18y&t=1h32m12s)
Does this strike you as similar to Raiden’s situation in MGS2. A battlefield machine that was only VR tested being put out into an actual battlefield. Could it be that all the reasons we were told as to why Raiden was chosen were a lie. And he was actually just a new model of bidepal/infantry/artillery. A new metal gear just not nuclear equipped!
