Can you set up your squad with the nubs hanging off the back edge of the map?
RRG:
p.12: "Each ship’s base has two pairs of movement guides, one pair on the front and one pair on the back. These guides are ignored for all purposes except executing maneuvers and overlapping obstacles and other ships."
p.11: "When a ship executes a maneuver or performs an action that changes its position, if any part of its base is outside the play area, that ship has fled the battlefield. A ship that flees the battlefield is destroyed."
If a ship performs a maneuver that puts its nubs off the map, it is destroyed (or is it? that's "executing a maneuver," but "overlapping obstacles and other ships" is also part of executing a maneuver, so calling those out separately implies that the first part just means you use the nubs to place the template).
Hurm.. this has expanded into a second question. if you put your nubs -- and only your nubs -- off the map, have you fled?
