The Marine Corps undertook so many of these missions after the turn of the century that in 1935 they published the Small Wars Manual to collect their experiences so that Marines could learn from it and use it in their own deployments.
Another example of this kind of operation was the deployment in of US
Army Rangers, Delta Force Commandos, at least one Navy SEAL, and the
associated helicopter crews
to Somalia. This effort culminated in an operation to capture associates
of a Somalia warlord on October 3, 1993. When the dust had settled,
18 Americans were killed and over 70 were wounded (the initial force was
about 160; the rescue of this force involved additional Americans from
the 10th Mountain Division, as well as armored vehicles from other countries
that were part of the UN peacekeeping force in Somalia). Estimates
for the number of Somalia dead are less precise, but the three most commonly-cited
figures are (a) 300, (b) 500, (c) ..this is the least cited figure.. – 1000.
