Army Officer Functional Area Careers
A functional area is a grouping of officers by technical specialty or skill, which usually require significant education, training, and experience.
An officer receives his or her functional area between the fifth and sixth years of service. Individual preference, academic background, the manner of performance, training, and experience, and needs of the Army are all considered during the designation process.
Here are some of the military occupational specialties (MOS) among Army officer functional areas:
Army Foreign Area Officers: Field 48
All branches of the U.S. military have a foreign area officer or FAO program, and the Army's is the biggest and oldest. They're grouped by areas of concentration, expertise and language skills. These commissioned officers are regionally-focused experts in military-political operations, which includes cultural knowledge, sociological insights, and geographic and economic awareness.
To qualify for an MOS in the Foreign Area Officers field, you'll need to be proficient in the language spoken in the region you plan to serve. You're likely to serve in a role where you assist and advise commanding officers on decision-making, such as a defense attache, a liaison officer or a general political adviser.
The MOS for this field include:
- 48B Latin America
- 48C Europe
- 48D South Asia
- 48E Eurasia
- 48F China
- 48G Middle East/ North Africa
- 48H Northeast Asia
- 48I Southeast Asia
- 48J Africa South of the Sahara
- 48X Foreign Area Officer (for otherwise undesignated regions)
