Read the following excerpt from a US court opinion:
```
v. Brown, 7 Vet.App. 476, 481 (1995). Although § 7722 does, by its terms, require VA to inform veterans of “all benefits and services to which they may be entitled” and to assist veterans “to the maximum extent possible ... in the preparation and presentation of claims,” the extent of such a duty will depend on the facts and law involved in a particular case. See Smith (Edward) v. Derwinski, 2 Vet.App. 429, 432 (1992). In this case, VA adopted certain duties as described in part II.B., above, with respect to pension benefits. In carrying out these duties, the Department also satisfied its general § 7722 duties when it informed the appellant in 1979 that he was entitled to pension benefits under the improved pension program and sent him the election card. See Gold, 7 Vet.App. at 319 ; Kluttz v. Brown, 7 Vet.App. 304, 307-08
