Thanks for the question. Most people use the ACU MOLLE hand grenade pouch, NSN 8465-01-525-0589, for their first-aid dressing. If they're carrying more supplies, such as tourniquets and hemacon bandages, etc, they'll use an M16 double-magazine pouch, NSN 8465-01-525-0606. To our knowledge, though, there hasn't been a direct replacement for the old first-aid pouch with the ALICE clip, which you used to get issued at CIF. (This was also the same item you used as a compass pouch, back when people used to carry compasses in the "BP" Before-Plugger Army.) You can find the complete list of MOLLE NSN's here:
