Army has the long action M24 ( off the 700), Marine Corps the short action M40 ( off the 40X).
My late night typo. The Army was using other M700s, short and long action, and Model 70s, long action and Magnum action, and 1903A3s, before there was an M24 ( 1988, IIRC). They had a brass catcher for all those, a cloth bag, with some spring clamp to hold it on the action, before there even was an M24.
