A mysterious "zap"

During my recent visit to Pratica di Mare, I noticed that many of the aircraft that attended the static display of the 87th Anniversary of the Aeronautica Militare, were “zapped” with a small gecko (or something like that) with the number “14°”. Since the aircraft were parked in the 14° Stormo apron my guess is that most of the visitors were zapped by the personnel of the locally-based Wing, but I’m still looking for someone that is able to confirm this hypothesis and to explain to which unit that symbol belongs to.

Aircraft zapped were:
MM7014/RS-01 Tornado IDS
MM55070/61-136 MB.339CD
MMxxxx AB.212
MM81267/72-04 NH-500E
MM55125/70-34 SF-260EA
MM55106/70-11 SF-260EA
MM61937 S.208M
MM55044/32-57 AMX-T
