Tank question!

[basola]

Hi guys! i'm tryng to understand how the land combat is working at 100% in il2.
reading the technics.ini, i've see that all armour had range 800mt.
the PzVI tiger I, was equipped with 88Flak18 adapted to this tank.
if you check the data about the 88flak18, it has setted the maximun range at 6000mt.
if you check the tiger's data, the maximun range is 800mt (with the same gun).
my question is.....all tanks range are putted to 800mt by a default setting (so it will be changed as well) or there are othr reasons (game plyability, bug, i dont know ).

Tnk, Andrea.
