Cost. Hindu Indian rockets are 15pts and Muslim Indian rockets are 30pts. They appear to be otherwise identical so which one is incorrect?
Deployment. Do they deploy first like other artillery, or at the same time as other units?
Range. In theory they can fire 72". Can you choose a target out to that range or is this the maximum overshoot range?
Movement. Can they move or pivot and are there penalties for doing-so?
Firing-arc. To target an enemy, do they fire in a narrow straight line, or a base-width straight-line, or in a normal missile-arc? Presumably they use the normal target-priorities and cannot fire blind.
Do they act as other artillery if shot-at or charged? Can they fight-back?
If a mounted-unit which is overshot by rockets passes its cohesion test, does it become immune to further such tests?
If a rocket-battery with a crew of 5 models scores a hit near an enemy unit, does it affect five 20mm circles or one 100mm circle?
