35,224 records (71.4%) have a known Branch of Service (Army, Navy, Air Force, Medical Health).
Branch is distinct from Corps (a specific arm within a branch, e.g. Infantry Corps) and Force (organisation/era, e.g. SADF). Most records not yet classified were recorded via a specific named Regiment/Unit rather than a generic branch label — this chart reflects only those directly identifiable as a branch so far.
