Over the past decade, we've finally been seeing the military take notice and adopt some of the advanced technology/high performance fabrics and clothing that civilian mountaineers and backpackers have been using for quite a while. Lighter, more compressible, breathable, quick drying and wicking fabrics now clothe the soldier, doing their part to make a tough job a bit more efficient and a bit less uncomfortable. Clothing the soldier presents a unique challenge as temperatures in certain regions may range greatly over a 24 hour period, or missions might start off at low altitudes and end up much higher. Soldiers most often have to be self-sufficient, carrying everything in their rucks and on their person, so light weight and clothing versatility rank high in importance. Unlike most sporting events, the soldier might have to wear the same clothing for days or weeks on end, and subject them to abuse that civilian use won't.
There are quite a few different clothing development programs out there, and it can be confusing. Since I have no personal knowledge on the subject, I've summarized some of the

ECWS - Extended Cold Weather Clothing System. Cold-wet and Cold dry systems, including the Gore-tex suit and insulating layers SPEAR - Special Operations Forces Personal Equipment Advanced Requirements - A performance layering system developed by SOCOM. MCPS - Multi-Climate Protection System - NOMEX flame resistant clothing for U.S. Marine and Navy aviators and aircrew. SOF-PCU - Special Operations Forces Protective Combat Uniform - Layering garment system with 7 Levels developed by USSOCOM. The different levels are defined as follows (from this website ). Also note that the actual products offered may vary slightly from these descriptions:

Level 1
Worn next-to-skin, a durable, silkweight Polartec Power Dry fabric worn next to the skin wicks away moisture and dries fast. It consists of a crew neck T-shirt and boxer shorts, or is available in long-sleeve top with invisible zipper and pants, built for comfort and minimal weight.
Level 2
A long-sleeve shirt and pants made from Polartec Power Dry fabric are worn next to the skin for extra warmth in extreme conditions, but still wicks away moisture quickly from skin and dries fast. An inserted side panel of Polartec X-Static fabric enhances fit and flexibility. The top has a front 15-inch zip for extra venting and a soft lining around the collar. Comfort features include an articulated side seam on the pants to minimize chafe on the kneecap.
Level 3
An insulative mid-layer jacket made from Polartec Thermal Pro fabric is water-repellent yet breathable. It is worn as an outer jacket in mild temperatures or as a heavy insulative layer in extreme cold. Seamless shoulders minimize chafe, which are then lined for extra warmth and padding for heavy pack straps.
Level 4
The soft windshirt is made from an encapsulated microfiber that repels water but also breathes for a variety of conditions. It's designed to pair with a next-to-skin layer for intense activity in cooler temperatures or with the Level 5 soft shell as a mid-layer. It stuffs into its own pocket for easy packing.
Level 5
The key to the entire system, this soft shell fabric jacket and pants are made with fibers encapsulated with sili...
