I am the wife of a serving soldier. We have 2 children and another on the way. I am the named beneficiary in case of my DH's death.
The attitude of these women make me so angry. I can understand that they might not like the mothers of their grandchildren, but they don't seem to understand that their grandchildren will go without their father, they never even got to meet their father, they'll never have a picture of themselves with their daddy, they'll never have the support of their daddy. As a serving soldiers wife this is something I deal with every time he goes away... "What if he doesn't come home?" And that isn't for me, it's for our children.
The money should be used to support the children, because like a previous poster said, their dad would support them financially if they had lived so should do in their death.
Many of the soldiers have outdated wills, but that isn't necessarily the job of the mod to sort out. That is their responsibility and perhaps they thought their mothers would never behave this way.
I have lost friends, I have lost people I love and seen the realities of war and the consequences for those who don't come home. Money will never replace them, but it can provide the children and/or widows with security. If my DH dies while in the army, we have 90 days to vacate our house and hand it over. I have seen widows go through this, i have helped them clean their houses and say goodbye to the last place they saw their husband alive. The money offers them security, a new start somewhere else with their children.
The mothers of the sons don't "deserve" the money. The children do.
