>Decoy Targets: Twice per battle, in your Movement phase, you can select one other friendly INFANTRY model that is on the battlefield and not within Engagement Range of one or more enemy units. The selected model is destroyed (ignoring any rules that are triggered when a model is destroyed) and this model is removed from the battlefield and set up again as close as possible to where that destroyed model was and not within Engagement Range of one or more enemy units. This ability cannot be used more than once in the same battle round.
How does this work exactly, and what is the purpose of this?
Do I just take a single miniature in the squad out and move it? A whole squad?
How close is close? What purpose does this serve?
