I have no doubt you know the diffrence between a Shpagin anda Bren, considering the distinct diffrences in design. However, it was more to point out how difficult it would be to get a Bren and a Shpagin mixed up.
And it does not seem impossible to me that the Chinese would use a Type 96 or Bren, and more than likely it was a numerical superiority and a difference in tactics. U.S Soliders, armed with BAR's and belt-fed Browning .30 Calliber M1919 MG's, still felt overwhelmed in the face of the massive numbers of Chinese troops that surged to their positions. Maybe what the vet was refering to was a personal experence as a rifleman, rather than a generalization on the Canadians as a whole.
