MARINE CORPS BASE CAMP PENDLETON, Calif. – Master Chief Petty Officer Michael Smith, outgoing command master chief of I Marine Expeditionary force, ‘goes ashore’ for the last time at the conclusion of his change of charge and retirement ceremony on Camp Pendleton June 3, 2016. Stemming from the naval tradition of requesting permission to leave the ship, ‘going ashore’ signifies the honorable retirement of a sailor from naval service. Master Chief Petty Officer Frank Dominguez, a Superior, Arizona native, is replacing Smith, a Ridgecrest native, as the command master chief of I Marine Expeditionary Force.

He’s a pillar of health, literally. At 6’3” and 210 pounds, armed with six years of college and eight years of military experience, Petty Officer 2nd Class John H. Holscher is a veritable tower of care and comfort for the people here, regardless of nationality. Not that any of them have a choice, because the next nearest medic is more than 100 kilometers away. 'The biggest challenge to being out here is being the only doc. (Iraqi) medics depend on me to train them, Iraqis patients depend on me, taking care of the Marines, going on every patrol, and then the villagers, I can’t take care of them all,' said Holscher, corpsman, Border Transition Team 4222. - He’s a pillar of health, literally.
