It is said that in WWII the Germans came to battle with a hunting rifle (M98 Mauser), the Americans came with a target rifle (M1903), and the British came with a battle rifle (Lee-Enfield). The Enfield M1917 is the .30-06 version of the British rifle and also an excellent rifle.
A little bit of a correction... the M1917 is the .30-06 version of the P-14 Enfield in .303, both which were used in WWI along with the SMLE and ‘03. The P-14 and M1917 were Mauser based actions, not based on the Lee action.
In WWII, the standard British arms were the Short Magazine Lee-Enfield (SMLE aka No1 Mk III) and the No.4 Mk I, which began seeing action in ‘41/’42.
Sorry to nitpick :-)
