Hm.. the Russian guns have an option for direct fire. However, I
was referring more to your supposition of relying on our
"conventional" guns for long range fire which I regard untenable.
Naturally, the Primus has to resort to shoot and scoot tactics as
per the commands issued to the Artillery firing unit.
As for a 52 cal version, they will have to do some serious tweaking
to the chassis. As it stands, 52 cal is a much longer gun compared
to 39 cal.
