Google promptly reshuffled Motorola Mobility's management Tuesday after completing its $12.5 billion acquisition of the device maker.

Longtime Google Inc. executive Dennis Woodside is replacing Motorola Mobility CEO Sanjay Jha as the company's leader.

Google also is bringing in several new faces while retaining some familiar ones at Motorola Mobility Holdings Inc.

Here's a breakdown on Motorola Mobility's regime under Google's ownership:

_ Woodside, the new CEO, spent the past three years as president of Google's Americas region, which saw its annual revenue rise from $10.8 billion to $17.5 billion under his guidance. Most of that money came from online ads. Earlier in his Google career, Woodside oversaw Google's expansion across Europe, the Middle East and Africa.

_ Vanessa Wittman is the new chief financial officer. She previously filled the same role at Marsh & McLennan Companies Inc., which sells insurance and business consulting services.

_ Mark Randall will be the head of supply chain and operations. He is a former executive at another cellphone maker, Nokia, and at Amazon.com Inc., where he oversaw the supply chain for the Kindle e-reader and Kindle Fire tablet computer.

_ Regina Dugan is running a newly created division focused on advanced technology and projects. She is the former director of the U.S. Defense Advanced Research Projects Agency, or DARPA.

_ Gary Briggs will oversee the marketing of Motorola's products. He directed marketing for Google's Chrome Web browser and previously led marketing for eBay Inc.

_ Scott Sullivan will lead the personnel department. He previously led the human resources department for credit- and debit-card processor Visa Inc.

_ Iqbal Arshad will lead global product development. He helped Motorola introduce its first phones running on Google's Android software.

_ Mahesh Veerina will continue to lead Motorola's software division.

_ Jim Wicks will run the consumer experience design division. He helped design Motorola's original Razr phone.

_ Mark Shockley will oversee the "go-to-market." He helped Motorola Mobility expand in Brazil and China.

_ Scott Offer will lead the legal division. He played an instrumental role in the company's spinoff from the old Motorola Inc. The other half, Motorola Solutions Inc., remains an independent company.
