I'm afraid to go there, but according to me there weren't any Indian soldiers or Indians of any kind in raiders.
I think you're confusing the movie with the Temple of Doom. Where at the last scene you have a Sikh infantry squad firing at the 'evil' Indian thuggee cultists.
I've got a few hardcopy print-outs of the script and after browsing through it I can't find any mention of Indian Muslim infantry.
Checking a couple of my books though I found a reference where is stated that the Muslim Infantry either wore khaki or yellow as the colour of their headdress. So the most historical Muslim Infantry colours would be yellow or khaki. Other then the Sikh colours of red and khaki.
