Editing Tank (section)

===Fording===
In the absence of [[combat engineer]]s, most tanks can only [[Ford (crossing)|ford]] small rivers. The typical fording depth for MBTs is approximately {{convert|1|m|ft|abbr=on}}, being limited by the height of the engine air intake and driver's position. Modern tanks such as the Russian [[T-90]] and the German [[Leopard 1]] and [[Leopard 2]] tanks can ford to a depth of {{convert|3|to|4|m|ft|abbr=on}} when properly prepared and equipped with a [[Vehicle snorkel|snorkel]] to supply air for the crew and engine. Tank crews usually strongly dislike deep fording, but it adds considerable scope for [[List of military tactics|surprise]] and tactical flexibility in water-crossing operations by opening new and unexpected avenues of attack.

[[Amphibious tank]]s are specially designed or adapted for water operations, such as by including snorkels and skirts, but they are rare in modern armies. Purpose-built [[amphibious assault vehicle]]s or [[armoured personnel carrier]]s are used, without tanks, in [[Amphibious warfare#Post–World War II|amphibious assaults]]. Advances such as the [[EFA (mobile bridge)|EFA mobile bridge]] and [[Armoured vehicle-launched bridge|armoured vehicle-launched scissors bridges]] have also reduced the impediment to tank advance that rivers posed in World War II.<ref>[[#Deighton1979|Deighton (1979)]], ''Blitzkrieg, From the rise of Hitler to the fall of Dunkirk'', pp. 234–52</ref>
