He stood and watched the cobbler at his trade,
The man who slices lemons into drink,
The coffee-roaster's brazier , and the boys
That volunteer to help him turn its winch.
He glanced o'er books on stalls with half an eye,
And fly-leaf ballads on the vendor's string,
And broad-edge bold-print posters by the wall.
He took such cognizance of men and things,
If any beat a horse, you felt he saw;
If any cursed a woman, he took note;
Yet stared at nobody--you stared at him,
And found, less to your pleasure than surprise,
He seemed to know you and expect as much.
The M2 is the second longest-serving weapon in the US military's arsenal after the M1911 , and is employed by over 60 countries worldwide. It has so far resisted all attempts to replace it, even replacing its own replacement in the case of the unreliable M85 heavy machine gun , while the later XM307 & XM312 and XM806 failed to enter production (the XM205 tripod developed for these weapons, however, did eventually get adopted as the M205, which is planned to replace the old M3 tripod for the M2 and Mark 19). The only major update to the ground-mounted version since its introduction has been the adoption of the General Dynamics M2E2 as the M2A1 (the export version is called the M2-HCQB) in 2010, with the main change being a fixed headspace quick-change barrel and fixed timing rather than the manually set headspace and timing of the original M2. The M2A1 also has a detachable barrel changing handle, a new slotted flash hider designed to increase the M2's compatibility with night vision optics, a modified bolt, and a manual trigger block safety (the original M2 has no safety, though operators would often make their own by jamming a spent casing under the butterfly triggers). Though the US military has not standardized a weapon called M2A2, several manufacturers market M2 variants under that name, such as US Ordnance (whose M2A2 has a closed-bolt semi-auto mode) and FN Herstal. Many modern guns are also fitted with aftermarket parts such as receiver covers with rail mounts for optics.
