The site is a total mess easy to miss all the links somewhere near the bottom there are links that show some inside views.
It does appear roomy & could probably operate as a short range battlefield taxi with a reasonable ammo load on board. However the ammo seems to be stored near the clamshell rear doors so once the magazine is empty you would not be able to reload till the passengers got out. Guessing here but not for use cross country unless you want injury more to drop off & support a patrol as a sign of strength, riding into combat I just cant see.
Wheres gingertanker when you need him.
