Just to reassure you, it's the arcade version. The NES version was never made available on the Virtual Console.
If you're curious where the "Wolf of the Battlefield" thing came from, I believe it has been retroactively applied to the original so it would fit in with the naming convention they used for Commando 3 when they released that here a few years ago. It's the translation of the Japanese name for the series (Which was always just called Commando over here).
If you want more, the sequel to Commando is also available on the Virtual Console and is titled Mercs. It's the Genesis version, which was a pretty faithful port of the arcade game. It also included an original mode with a new plot and all new stages exclusive to the Genesis version.
Although if you have a PS2 or Xbox, you'd be better off buying Capcom Classics Collection Volume 1. Probably will run you used just about what you'd be paying for that Virtual Console arcade download and includes the arcade version of Commando and Mercs (On a physical disc, with 18 other classics). Here's the lineup.
