It appears that special units, like 41 Commando, that worked directly with American units, used the American weapons while larger units working simply under the UN Command retained the British weapons. This makes sense, since I am assuming these special commando units were probably better trained in “foreign” weapons use to some extent even before receiving the American small arms. Training normal units in the use of weapons preiously unfamiliar to them, especially in the harsh Korean Peninsula climate, may have been problematical.
That is an interesting article. Thanks for posting it. Some minor technical errors (“1926” designation for the 1928 Thompson; “M1919A4” for the Browning M1919A6 LMG with buttstock, etc.), but they did not detract at all from the overall interest of the article.
I would rather have an M1 Garand than a No. 4 Enfiled under any circumstances, although I admit that my favorite bolt action military rifle for practical combat use is the Enfield. It must have hurt to give up those Bren guns though. The BAR is a good, reliable weapon, but in the American version, not without faults. The Plish and Belgian versions are somewhat improved. The Bren, and its Czech counterpart, are, in my view, far superior though. JMHO.
Interesting thread, at least to me!
