Although PALS webbing on kit is fairly standardized, the connection styles are not. Since the original MOLLE "Natick" style snap is patented, other manufactures have come up with different connection methods. However if you are just making gear for yourself, feel free to use whichever style you prefer or even experiment making your own.
-MOLLE "Natick" Snap:
This is the standard issue and most well known method. Using classic snaps and manufactured by Speciality Defense Systems. Overall simple and work well, just in the long run your snaps may deteriorate. While weaving MOLLE snap pouches onto kit, sometimes the snaps can snag and slow things down. Products such as Magpul's Speed Threader were made to assist in this issue.
1-27-2007: Added Military Green color comparison sheet. There are some semi new greens out there so I thought I'd make a sheet displaying all the major military greens.The most known and common is OD standing for Olive Drab. This is a fairly brown / saturated green. The Airforce went with what they call Sage Green which is a much more grey green. Sometimes things are labeled OD, however really are Camo Green which is a more blue-ish green as seen in Woodland Camo. One of the more modern colors which is popular yet has no widespread military use, is Ranger Green. This green is a more brown and desaturated OD. Paraclete calls their green Smoke Green, but generally looks very close to Ranger Green. Adding to the pile, Emdom uses Sewer Green which is a midpoint between OD and Ranger Green. I added in a UCP / Foliage Green sample for your reference. As you can see...it is a lot more grey than anything else.
