While watching an old Komatsu work at our field, I came up with an idea I've never seen used in any post-apocalyptic setting... Battle Excavators!
I mean, there are tanks in Fo:Tactics, Soldiers of Anarchy, STALKER etc, but after the apocalypse, wouldn't they be a lot fewer in numbers when compared to the common and cheap civilian working machinery?
An average excavator could be easily turned into a capable weapon of destruction with a few upgrades. Here's an image of a quite common one:

Imagine if the glass around the driver's seat was replaced with iron / steel sheats, plates or whatever, with little "lookout-hatches" on each side, just like in tanks. This one would be pretty easy to do with all the metal junk around. Next you'd add a mounted machinegun either on top of the "driver's cabinet" or on the backside of the vehicle.
The reaching claw could be used both in peaceful and less-peaceful purposes... To dig ditches and stuff OR crash other vehicles, walls and people. The backside of the excavator is made of heavy steel by default, so there isn't really any need to make armor upgrades on that part. This vehicle would be invulnerable to normal handgun & rifle rounds + it's very common and cheap to turn into a potential war machine.

I'm not sure, in which forum this should be added, so I'll just post it here in GD. So, what do you guys think of my idea? Should I go and start selling it to the people at the STALKER, Fallout3d, [insert post-apoc project name here]-project or simply shut the fuck up?
