I recall reading somewhere that 75% of Israeli arty missions in 1973 were counter-battery fires.

175mm would likely be reserved for such. A scenario designer should be able to make such batteries CB-only by reserving them at higher command as reserves with an arrival time after the scenario end. Thus the player does not get to sidetrack the GHQ-level counter batteries into on-map supporting fires.

Israel was a bit tank-heavy and infantry and arty light at that point, after the 1967 experience. Therefore, I think that the only direct support fires they would tend to get (unless in an attack or assault) would be the relatively few SP 120mm mortars in each battalion, + maybe a battery off off-map 105/155 under player command.

(After 1973, Israel "rediscovered" infantry and arty once more)
