20.3 states: "Onboard Mortars (WTs only) can also place Starshells (pending Nationality Capability), but a GO Leader or Scout must use their impulse to call-in the fire. The Leader/Scout can place a Starshell marker in any hex within THREE hexes of his hex or in any hex in his LOS under a Fired marker that is also within range of the Mortar (no roll is made).
I'm not sure I understand the sentence "pending Nationality Capability" here. As I could understand, using a Leader to direct the Mortar WT would automatically place the starshell (no roll is made). Can a Mortars WT place a starshell by itself (without a Leader directing the fire) in a hex with a Fired marker? If so, no roll is made too? If I take the sentence literally, the "but" conditions the starshell placement to the direction of a GO Leader, so that a WT wouldn't be able to do it by itself. Is that so?
