Not Exactly What It Says on the Tinnote : When someone who no longer fights on the front lines, perhaps because they got promoted to a desk job, or decided that they were getting too old for this and retired, returns to battle, either out of boredom or necessity. Can often apply to The Captain, a Four-Star Badass, or maybe even The President or the King.
Related to 10-Minute Retirement. In the case of Back in the Saddle, the retirement or promotion typically won't happen in the same story arc as the return to the action. This trope also applies to being Kicked Upstairs or being otherwise made into a Desk Jockey.
- An unusually young example, but... in Zeta Gundam, Amuro Ray - the Ace Pilot from the original Mobile Suit Gundam - is retired, and living in virtual house-arrest, since the Terran Government suspects that he might have spacer sympathies. As it turns out, they're right - after an encounter with the new hero, Kamille Bidan, he decides to join up with the AEUG, and jump back into the pilot-seat of a Humongous Mecha. (Though, sadly, he didn't retrieve the original Gundam from the nearby museum as many probably had hoped.)

CaptainAdmiral Kirk, who's been working a desk as Chief of Naval Operations for several years, uses the V'Ger crisis to get himself returned to the Enterprise. This is a subverted example in that Admiral Kirk is not in fact in command of the Enterprise, but rather is in command of the mission the Enterprise is on. Captain Decker has the responsibility (and arguably, the fun) of commanding the ship itself. Furthermore, it gets Deconstructed because Kirk has been behind a desk for several years, and thus his instincts are rusty, on top of the ship having been so heavily redesigned and refitted that she is no longer the ship he spent five years commanding anyways.
