Okay after reading the CRB and Hammer of the Emperor over and over again there are still some realy big questions on my mind.
Why is the range for a Leman Russ BATTLECANON listed with 350 meters? We'r talking about the Main Gun of a MBT here and not a simple heavy stubber. Same goes for the Earthshakerr Gun. Discriptions tells that it is a piece of "superior long range artillery" but the range chart tells us that it is in fact just a piece of short range anti-tank weapon with a range of 3.5km (3,500 meters). Compared to a modern day german Panzerhaubitze 2000 (max. range 30-40 km = 30,000 to 40,000 meters) this is next to nothing.
Same goes for every singel heavy weapon from autocannon to mortars and missilelaunchers the listed ranges don't make any sense.
Perhaps some of you fine folk can sheed some light on this matter.
