How about:
“Supreme leader, we have tracked their reconnaissance ship to the Ileenium system.”
“Good, then we will crush them once and for all. The resistance must be destroyed before they get to Skywalker. Prepare the weapon.”Or shorter:
“Supreme leader, we have tracked their reconnaissance ship to the Ileenium system.”
“Good, then we will crush them before they get to Skywalker. Prepare the weapon.”
Even shorter:
“Supreme leader, we have tracked them to the Ileenium system.” [if “them” can be created]
“Good, then we will crush them before they get to Skywalker. Prepare the weapon.”
