Wikipedia:Incremental service awards
Unlike the Standard Unofficial Service Awards these awards are used to allow the users to have awards in-between the Major service awards.
Currently there are 20 incremental service awards, 4 levels each for the first 5 service awards. The images for further incremental service awards still exist (although the templates are not available) - check this for their use.
To keep the validity and status of the major service awards, a ribbon is the only variant of the incremental service award.
