LOS ANGELES — From sea to shining sea, the nation paid tribute to its members of the armed services Sunday, both with somber traditions such as a Virginia wreath-laying ceremony attended by President Barack Obama to honor those who didn’t make it back from active duty, and more lighthearted perks including red-carpet treatment at Las Vegas casinos for those who did.

In California, a long legal case drew to a close as a war memorial cross that had been deemed unconstitutional was being resurrected Sunday in the Mojave desert, capping a landmark case for veterans fighting similar battles on public lands.
