The thing about tanks versus other combat arms jobs is simple
tank crews are usually tighter knitted. Yes, I know, infantry units consider each other brothers, etc. But in a unit the size of an infantry one, there's 50+ in one platoon, broke down into squads, then fire teams.
I've worked with infantry, artillery, etc. Nobody's closer knit than us.
a tank platoon is 4 people in a tank, eat, sleep, etc in a tank, you get very close to them. I know the crew just as well as my own family.
big unit runs? Some unit platoons outsize a tank units whole company of 3-4 platoons
though, I am excited for this. Finally a (with all due respect to airborne) war movie about tanks and not the same ol' airborne movie
I am actually very amazed from the trailer about how much has changed (and how much really hasn't)
