Rough Speeds.

[Marek_Tucan]

For example I have found "elsewhere" (www.wwiitanks.co.uk) M3 Halftrack (or more precisely M3 75mm GMC) cross-country speed stated at 35mph, which is ca. 56kph. Unfortunately the source doesn't state cross-country speeds for 250 and 251 but given stated roadspeeds (37mph for 250, 33 for 251)... So the sources (and even the very definition of cross-country speed) may and do vary.

For a modern example, as a firefighter I recently drove our rescue unit in full emergency response mode on a paved road through our city during a period of very light traffic. Top speed never exceeded 40 km/h due to pavement heaving due to spring frost conditions. Vehicle speed is based entirely on conditions at the time and has nothing to do with published specs of any sort from any source. On that same day I am quite sure my off-road speed would have been much faster and the ride would have been infinitely more comfortable!
