Probably Wells’s The War of the Worlds.
Interesting question, Baylor. You might want to say something about how you would like “classic” to be understood.
Read that when I was in the Army. Not sure if Heinlein had military experience, but he captured life as a soldier quite well.Before I become a fan of the genre, The first purely science fiction book I read was Starship Troopers by Robert Heinlein . I finished the book and I liked but didn't make a devoted reader out me, That came later.
Ender's Game always counts.Does Ender's Game count? If not, then Dune.

Didn't get into Sci-Fi until around 16, though I had reading assignments in school that included works by H.G. Wells and the like.
First book that got me into the genre was Deathbird Stories by Harlan Ellison. Fell in love with his style; witty, caustic, and made people look at life in a different lens.

Not that you asked me, but I would suggest classic sf to have been written by a well-known author in the field, whose work has advanced the genre, and also a book which is well known among the sf community, and perhaps outside it. Who, after all, does not know War of the Worlds, The Time Machine, 2001 (yes I know but you know what I mean), hell, even Star Wars could I suppose qualify on the second criterion if not the first. Clarke, Vonnegut, Wells, Verne, Wyndham, Bester, Heinlein.. these kind of names, to mention but a few. People now seen as role models by today's authors.Probably Wells’s The War of the Worlds.
