security specialists killed in the line of duty as of July 2006. The vast majority of DSS casualties had taken place within the five years in Iraq, where DSS continued to conduct its most critical and dangerous protective missions. It should be noted, however, that the Regional Security Officer title is currently in an unofficial period of flux and, although not officially sanctioned, some agents posted overseas use derivative titles such as security attaché or only use their agent titles on their business cards. Newer agents generally dislike the title, because it doesn't reflect their law enforcement status, and consider it a vestige of Diplomatic Security's SY days. According to U.S. law, the title "security officer" is legally defined as someone who is employed by a private entity and is not a law enforcement officer. Additionally, it is noted that RSOs no longer cover multiple countries and are thus not regional. Even some more seasoned agents have taken to referring to themselves as Special Agent-in-Charge/Regional Security Officer on their official biographies. The method in which the RSO title is implemented also has the potential to create confusion when interacting with outside organizations. It is possible at larger overseas missions with multiple diplomatic facilities located in the same country to have multiple agents with the Regional Security Officer title. India, for example, has an RSO position at the embassy at the Senior Foreign Service level and 4 other RSOs at the consulates at the significantly lower grade 3 level yet all of these agents have the same job title. Sometimes the title Senior Regional Security Officer will be used to help prevent confusion or to indicate that the agent is the most senior in the country. Overseas Criminal Investigations Division The OCI manages all DSS investigative forces abroad, namely Assistant Regional Security Officer-Investigators (ARSO-Is), DSS special agents responsible for ensuring the integrity of the U.S. passport and visa system. Embedded in 120 diplomatic posts across 85 countries, there are roughly 130 ARSO-Is who conduct criminal investigations and work with foreign governments to build a global law enforcement network; they maintain formal partnerships and training programs with foreign police, immigration, and customs officials to target a wide range of criminals, including forgers, smugglers, and terrorists. The division's prevailing goal is to "combat crime where it originates rather than waiting for it to cross U.S. borders." With its global partners, ARSO-Is help locate
