In a number of countries where they've developed single access points for veterans with information on services, they would generally have that information available for widows. One of the issues in many countries is that once the veteran dies the widow is quite generally entitled to all the benefits, pensions, and so on from the deceased spouse. It's a minefield for those people to go through, in terms of wanting to know.
In countries that have developed a central point of referral, quite often it's for information or counselling lying within the departments of veterans affairs, and that's where it occurs.
