Tom- This is a passage from Cap'n Laughton's paper on the sharpshooter battalion of Mahone's brigade from the Southern Historical Society Papers- I would suggest that their repetoire of battle skills not only included sniping but night ops as well-at first I thought they were using Kerr rifles, but have since been convinced that they were using regular .58 cal 2 band Enfields and the Pritchett bullet- there was one instance mentioned where 800 sharpshooters held off a Union Corps for most of a day-Barrett

The organization thus completed consisted of five companies, with eleven officers and 180 enlisted men, and served as a separate corps during the remainder of the war, being subject to the same regulations as the regiments of the brigade, except that they drew their rations and commutation from their original companies.
The battalion was armed with long-range, small-bore Enfield rifles, and used a long English-made cartridge. We never used any ammunition made by the Confederate Government. There were, besides, two globe-sighted rifles for use on special occasions, which were valuable additions to our armament. I have frequently fired these with entirely satisfactory results.During our occupancy of winter quarters, previous to the Mine Run engagement in May, 1864, our time was spent in perfecting ourselves in the

and in rifle-target practice at different ranges--from fifty yards to 1,000 yards--and so proficient did the men become in estimating distances that, although the chain was used to confirm their calculations, its use was finally discontinued as being unnecessary. Every day these practices were kept up under strict discipline, and systematic regulation and improvement in markmanship noted, and such men as failed to make satisfactory progress were returned to their companies and others substituted, so also, when the casualties of battle decimated the ranks, other details were made from the regiment in which the loss occurred, thereby keeping up the full maximum of strength. Thus, when the campaign of 1864 opened, this body of 180 officers and men, selected for special duty and because of eminent qualifications for such service, appeared thoroughly trained and fully equipped, and their subsequent record proved that they were absolutely invincible in every engagement in their history, never having been driven from their lines in any single engagement.
