FC is worthless for off-map units (it is for direct fire)
RF is ditto worthless for off-map units
ROF is worthwhile for both <g>!
Gun ACC value is not worthwhile other than for direct-fire point-target on table missions, either.
gun ranges >= 200 are really only relevant for counter-battery fire between off-map units. They can fire all over the map if on-table assets. Are irrelevant really to on-map arty.
Burst fires - are not really done by this game system. (If so, then the S-tank and the French FL-series autoloaded turrets would have good initial bursts, but the latter at least required bombing up from a hull store, out of fire - and so no real way to simulate with the current mechanisms - and especially try telling the AI how to reload an AMX-13 ?!?
The Swedish bandkanone, as I recall has a 14 or so ROF - and so should empty its 155mm magazine in 1-2 turns..
