Its a rather odd situation regards veteran groups, funerals, memorials, etc. Luftwaffe associations (and the veterans) for example, are very respected by current day pilots and involved with the occassional significant event. Such as when the Bundeswehr got F-104 fighters. Funeral honor guards of current military personnel can be found when an important WWII personality dies.
Not so the case for Waffen-SS veterans. HIAG is now dissolved and has been for a number of years, replaced by the Social Work Paul Hausser. It is more a functioning financial entity than a group of associations as HIAG was. Veterans associations still exist, though some, such as that for Junkerschule cadets, dissolved due to lowering membership. This month was the final Regiment "Der Führer" annual reunion. It met for over 30 years in Lenggries every year and was welcome by the local townspeople. A radical article in a newspaper caused bad press, threats, and other problems in the mid-1990s and the group moved its reunion to Austria. "Totenkopf" does not publish their reunion location due to harrassment by younger radical political types towards the vets. Portions of the LAH, III.Korps, cavalry, Engineer , I.Korps and Pz Rgt 5 associations among others still meet. But many of the 12-18 associations have or are fading due to age, difficulty in travel, etc of the veterans. Many are very small and the meetings not as grand as even a decade ago. Some only involve a dozen people attending. All I've attended, by invitation, include a ceremony for fallen comrades, generally held outdoors at a cemetary or memorial. Few Waffen-SS associations are allowed any type of fallen comrades monument and those that have one are restricted to not being allowed to use the term SS in the unit title of the stone or memorial. Germany seems to hold a stigma towards the Waffen-SS more than ANY other country. A number of British reunions of vets invite for enemies from the Waffen-SS. But note any SS book published in Germany. Covers are not allowed to incorporate a photo with an obviuos Siegrunen and specific other topics, a rather odd law to restrict a historical text. Funerals for SS vets receive little or no publicity, the vets attaend the funeral and wish to avoid protests and problems during the service. Often the veterans have a small honor group, obviously in civil cloths, with one carrying a funeral pillow displaying decorations. Often a significant individual, such as a Knight's Cross holder, representing the deceased unit attends, a tradition that is important. Many families consider the important people who attend the funeral and indication of the impact the deceased had and many funerals have a photographer record the event.
