Joe Gill--After the Human Torch, What?

This is one of the features Joe Gill wrote at Timely/Atlas after the Human Torch revival. The only story in Spy Thillers that I can't make out as his is the backup in #4, which is actually a war story--it may have been brought over from one of the battle mags.

"This is" in captions is one of  the clues to Joe Gill--here you see it in "The Double Identities" and "Oil!" In the same tier in the latter you see it in the past tense too, as you're more likely to see it in Gill's Charlton scripts.
