Crane's poem includes a "refrain?" Yes or no

YES

Explanation:

I see two refrains in this poem.  They are "Do not weep" and "War is kind."  Both of these refrains help to point to the major theme of the poem -- the idea that war is a devastating thing that destroys people's lives (and the lives of those who are left behind).

If war were really kind, the speaker would not have to tell the listener not to weep.  But war, the ironic title of the poem notwithstanding, is not kind.  It causes people great pain for no good reason, Crane says.
