During WW 2, there were many fire fighting platoons in the US Army (includes AAF) and it appears at war's end, the FF plts had 4 digit numbers. These FF plts were assigned to the engineer branch. This is most likely a badge belonging to to a GI in a FF plt.
As stated previously, the 27 may be the badge number - after all, civilian FDs had numbered badges (as did some MPs, like numbered PD badges), and the VMP refers to the station of assignment. Since the 27 and the VMP appear to have been inscribed subequent to the manufacture of the badge, it doesn't seem likely to be for a specific, numbered engr unit.
In a 2005 article which was published in The Trading Post, it was indicated that the Army had, in addition to Army base and post FDs, engr avn FF plts, AAF base utility dets; and companies and plts assigned to FF missions.
