CBO said in a report released Friday that DoD saw a 47-percent increase in O&M spending from 2000 through 2012, driven by the Defense Health Program and combat forces-related activities.
Derek Trunkey, an analyst at CBOâs national security division, presented the report at the Western Economic Association Internationalâs 91st annual conference in Portland, Oregon.
CBO classified the Pentagonâs O&M funding data into four categories that include purchased goods and services, activities supported and sources of products and services.
According to the report, activities in support of combat units accounted for 12 percent of $198 billion in total base budget O&M spending in 2012.
Maintenance, technical, transportation, medical and research services represented approximately $91 billion or nearly 50 percent of the total base budget O&M purchases in 2012, CBO said.
The report also noted that 66 percent, or $72.2 billion, of the total external revenues related to working capital funds in 2012 came from base budget and overseas contingency operations O&M funds.
