WW2 photographs unknown regiment? commando?

[bananamafia]

could anyone help with these recent house clearance find?
They seem to be WW2 era and feature the same guy, but i cannot work out what the cap badge is.
also, in the group shot, they all appear to be wearing the rubber sole "commando" type boots??

the back of the group shot is stamped:
"Photo Anouchian - autorised services photographic - dealer No 20" and "approved by HQ ninth Army"

any pointers appreciated.
