Note, there is a notes slide with some extra info that was not there. Also I know I have 1 mech and a tank but they are both under classification of armored vehicles. Links: A1 mech: https://scratch.mit.edu/projects/1276111311/ RT-a: https://scratch.mit.edu/projects/1272277066/
I am aware that the RT-a does not have much info and that the A1 mech was originally operated by 1 man, but now it's 2 as both crew members operate the tank and fix issues along with operate weapon systems and drive it separately.
