Whilst searching for more information about the 'Nacho Wars' I came across this period photo which purports to show a patrol of Republican infantry on patrol in the Burrito Valley . Like a lot of photographs of this conflict it is probably posed especially for the photographer . The infantry are wearing the 'grey' uniform which is actually white with a faint blue stripe (similar to the Spanish uniforms worn in the American-Spanish War in Cuba ) which at a distance appears a pale grey . The puttees are a darker colour , either dark blue or green . The French type helmets are khaki or Horizon blue .
