Sissiradistikilta is a special training branch guild for Finnish Defence Forces sissiradisti trained troops. The Sissiradistikilta Guild was founded in 2017, the centenary of independent Finland.
Sissi units’ main task is to perform reconnaissance and intelligence operations. Although many times dubbed as ”guerrilla units” due to the tactics they sometimes use, sissi troops are a regular part of the Finnish Defence Forces and nowadays the term is mostly used to mean reconnaissance units.
Sissiradisti, which meaning mostly corresponds to the concept of reconnaissance radio operator, is the name for specially trained signalists within these troops, and as so, some of the Guild members have interest towards amateur radio (see Station OI6S).
