One has only to look at tanks like the M3 Stuart with people around them:<p><a href="http:&#x2F;&#x2F;afvdb.50megs.com&#x2F;usa&#x2F;pics&#x2F;m3stuart.jpg" rel="nofollow">http:&#x2F;&#x2F;afvdb.50megs.com&#x2F;usa&#x2F;pics&#x2F;m3stuart.jpg</a><p>It has a crew of 4. I believe you can see the driver &amp; codriver through the viewports under the turret.<p>Then compare to an M1:<p><a href="http:&#x2F;&#x2F;www.cybermodeler.com&#x2F;armor&#x2F;m1&#x2F;images&#x2F;m1_002.jpg" rel="nofollow">http:&#x2F;&#x2F;www.cybermodeler.com&#x2F;armor&#x2F;m1&#x2F;images&#x2F;m1_002.jpg</a><p>I wish I could find a photo of them side by side
