I just posted about IRR callsign patches on our blog. Instead of the standard white square that you wear on your kit when looking through II, they clearly show the callsign. We're not selling them (except in bulk at unit level) so not a sales pitch, but I think they're quite interesting for two reasons: Is there any point for most operations/units? Quite a useful picture-paints-1000-words IRR powerpoint slide, for the use of. Also, out of curiosity have any regular units already got these?
