Hi Guys. I know the RFC/RAF used tracer and incendiary munitions when dealing with Zeppelins however, when did tracer become standard ammunition, especialy for all MG use? It has just dawned on me, I have seen many photo's of the Somme 1916 and Passchandaele 1917 battles however, I do not recall seeing any revealing tracer splash from MG fire. Some of these MG barrages were collossal! 1 x MG barrage at Passchandaele, involved a non stop 1,000,000+ round MG barrage involving 50 x Vickers HMG's in the semi indirect mode. Captured POW's said it was most demoralising!! If tracer was in use then, can you imagine the firework display? When and where did tracer become standard MG ammunition?
