I've just put my crew and their ride up. Had a lot of fun making them all, and I think they'll be a lot of fun to play around and interact with too, they seem like a colourful bunch. 
I have no idea where I came up with the name of the tank from, but I honestly love it.

I forgot to add the shotguns to the inventory, dammit.

I didn't specify extra weapons carried on the Leopotamus, but I'm going to assume they're toting around some stuff as extras.

I love the M60. Saw this recently

Oh, I love that!

I will be acquiring upgrades for the tank as we go on in this thread. The crew will be Strategically Transporting Equipment to Alternate Locations.

I could have put a lot more mods onto my tank, but I figured that I wanted to have something to build up to as we go, so I've kept it relatively minimal for now, and will get more exotic and complex as we go on. Especially since there's a lot of modifications and upgrades to the Leo 1 IRL.

Maybe a m109 or a Panzer Geppard... the 35mm AA tank.

Those are both excellent choices. 
If you're interested in an SPG, I always loved both the PzH 2000, and the South African G6 Rhino (which looks like a sci-fi vehicle!)
