Quick Canon Question + Icons

Quick question on Agent Carter canon, though more of an opinion than anything else:

In Season One, Jarvis says he was 'aide' to a General in Budapest. I assumed that he meant 'aide-de-camp', which is a sort of secretarial position, but I recently saw Jarvis mentioned on TVtropes as a 'batman', and that actually makes a lot more sense (batman was a servant to an officer, in charge of running errands, driving him, taking care of his clothing, digging his foxhole in battle, etc.). Did the AC writers use 'aide' so not to confuse American audiences, who probably would have gone to Bruce Wayne at the use of batman? It just makes more sense to me for him to be a batman, and go into life as a butler (historically, batmans often followed their officers into domestic service), than to be an aide-de-camp, which was a very prestigious position, and then have all the skills to be a butler later on.

Any thoughts?

Also, while I'm here, I said I was going to make some Ana Jarvis icons and I did. If any wants them, please feel free to use. Credit to songstressicons and/or citadel_icons if you'd like, but it's not necessary. Also, I'm trying to get the hang of a new graphics program, so if anyone would like any other Agent Carter icons, I'm happy to make them if you give me a picture or subject.
