Yes, it does look like a HE-pack.
But on the screenshot above we see the Medikit... then he says that TFTD had nice Medikit handob... and then asks why OpenXcom couldn't have the same thing? Also at the beginning he says that it bothered him that soldiers carrying medikit had a grenade in hand...
Except for the very last line of text, everything is about medikits.... that's why the confusion.
