Horwitz's Battle Action #68 and Marvel's Battlefront #3

The cover to Horwitz Publications' Battle Action #68 is illustrated by Maurice Bramley:

This issue reprints the four stories in Marvel's Battlefront #3. The four stories - Spearhead!, Kill Or Be Killed, Breaking Point and Follow-Up - are chapters of a single story, written by Don Rico and illustrated by Jerry Robinson, and told from the perspective of a tank.

There are two advertisement dates in this issue - B.A /7/60 and H.C/8/60 - suggesting this issue was published shortly before July 1960.
