Yes , it is unlikely that the Kfz 1/20 would be used/was used on any sea.
However because IL2 does not catalogue water depth , vast floodplains of shallow water ,
and very large rivers and lakes were navigated by this vehicle -that was the purpose of its design.
If it simply requires an object of a different name to be entered in various IL2 object categories ,
it would be simple to name it Kfz 1/20 in the vehicular categories
( Stationaryobject , object , vehicle) and Schwimmwagen in the ships categories ( Ships , Stationary Ships).
Would this function properly ?
And we do not address an issue fundamental to IL2 - AI fighters not armed with ordnance will not attack ships , even if given
explicit waypoint directives in the FMB or if ordered by a human fligtht/sqdn leader in-game via the Tab Key commands.
It would be much more elegant to remove all fighter FM restrictions preventing AI fighters strafing ships , should either of
the above criterai ( FMB GAttack Waypoint attached to enemy ship OR Tab Command Key directives to Flt or Sqdn to
Attack Ground Targets /Ships ).
(sorry zFlyer for diverting thread , but I feel the situation of an amphibious vehicle (Kfz 1/20) warranted the mention of
this issue).
