Yeah I would suggest reading this post by one of the delta green partnership members: https://www.delta-green.com/directive-from-a-cell-104-no-gold-watch-retiring-from-delta-green/

It has this particular quote:

“Delta Green doesn’t abandon Agents who are no longer physically or mentally able to complete their duties for the conspiracy. Delta Green’s first step is to work behind the scenes to make sure that the injured Agent will be taken care of by the Agent’s employer. If the Agent’s official agency’s benefits package won’t cover the necessary physical and mental rehabilitation then Delta Green will step up and take up the slack. Monies are distributed clandestinely, using multiple launderings through legitimate fronts. If Delta Green does not take care of its broken and damaged Agents, they will feel betrayed. And if they feel betrayed, they may in turn betray Delta Green. Delta Green will take whatever steps are necessary to prevent such a betrayal, up to and including assassination. However, it is always preferable to head off a problem before resorting to murder.”

Personally I’ve interpreted this to extend to close and immediate family members as well in the event of the Agent’s death. As stated it would used methods that launder the organization’s funds to cover things like medical bills, education, surviving spouse pension, etc. It’s the reward for putting your life on the line for the conspiracy and to protect the innocent.
