Job Interviews: Military Edition, MOS 3521

USMC Sergeant Jeffrey MacAuslin currently works in Scarborough, Maine, as a recruiter. After he completes his 3-year commitment as a recruiter, he’ll return to “the fleet” as a mechanic, working on the Marine Corps’ biggest and baddest trucks.

Below is Sgt. MacAuslin’s interview:



Also, I thought some of you might be interested in the trucks that he works on, so here are some pictures:

A Cougar MRAP 4×4. Powered by a Cat C-7, 16 tons, and a top speed of 65 mph.


A M1114, better known as a HMMWV, or Humvee. 3 ton, 6.5L Turbodiesel V8, and a top speed of 55-70 mph. The improved and slightly different variants include the M1151, or the Humvee 2.0, the M1152, which is the truck-version, the M1165, which is the ambulance/radio/anything else Humvee, and the M1167.
This is the MK-23. With many many variants of the truck, some include; dump truck, tractor, wrecker, resupply, flatbed, and HIMARS systems. Powered by a 12-Liter I-6 Turbodiesel Cat C-17, the 15-ton truck is capable of 55mph.

A MK-37 equipped with the HIMARS system.
A M1161 Growler. A lightweight, fast, and agile machine capable of quick entries and exits. I-4 Turbodiesel, and capable of 85 mph.
MKR-18, one of the largest trucks in the USMC. Developed by OshKosh, it is powered by a 15.2-liter I-6 Turbodiesel making 600 horsepower and nearly 2,000 ft-lbs of torque. This truck, when loaded, weighs nearly 100,000 pounds.

(And that is just a couple of the trucks involved. There is much more, let alone the variants and specifications that each truck has.)
