Batman has been forced to tighten his belt for some time now. Ever since the Joker War, his resources have been significantly limited, and that only continues in the pages of Batman #139 (by Chip Zdarsky, Jorge Jimenez, Tomeu Morey, Clayton Cowles). After breaking away from his family, Batman found himself going back to basics. He maintains his own gear, operates alone, and even monitors things through the police radio. It feels very much like he has been forced into a more limited role than he has been in years.
