Are they Romanian?

[PoorOldSpike]

I'd like to put this pic in our Photo Section, I presume it's WW2 and I'd like to add a caption giving their nationality, anybody got any ideas?
That MG looks interesting too

I can only identify the "MG". It is a AT-rifle Solothurn S-18/100.
A good picture at: http://world.guns.ru/atr/atr008-e.htm

As Wiki says they were sold to Hungary and Bulgaria (http://en.wikipedia.org/wiki/Solothurn_S-18/100). Maybe troops from there? Cavalry?
