Jarhead, I will give you a brief description and estimated cost of the gear Bruce Willis is wearing, if you could find detailed pictures of others that you want gear identified just post and I will see what I can do.
This is not a complete breakdown, just some of the most obvious stuff. As far as I remember the movie makers at first attempted to buy a lot of gear from Eagle Industries, but afterwards they bought a lot from Blackhawk Product Group, I think they figured it was cheaper from BPG for similar stuff anyways.
A. Ranger H-Harness, BPG and Eagle both makes this, cost new can range from 40-90 USD, but as usual (this refers to the rest of the post too) look for it on eBay, it will be much cheaper there.
B. Locking D-ring, variety of companies will make this item, just look for one that looks like the one in the picture. 10-20 CDN
C. It is common for US Special Operations units to move all 4 pockets of their combat uniforms; they then move the bottom 2 pockets to the breast and then move the 2 breast pockets (smaller ones) to the arm. Now it is popular to add Velcro to the pockets that will get moved to the arm, but for TOTS no Velcro was added. If you do it yourself, costs nothing, otherwise it will depend how much a local tailor would charge. Try to find some tailors in Chinatown, they are considerably cheaper.
D. Black drop leg holster, BHI and Eagle both make this as well as many other companies, your obviously looking for one in black. Costs, 60-90 USD new
E. US issued Alice triple M16 mag pouches, these can go for as little as 5 CDN and as much as 20 USD
F. US issued belt, as little as 5 CDN to as high as 20 USD, eBay is your best friend for stuff like this
G. Double pistol mag pouches, probably kydex inside, variety of companies make these as well, costs can be 20 USD+ each
H. Likely to be a Underarmor sweat wicking shirt, costs are probably 40 CDN+, mine was about 50 CDN shipped
Footwear: It is not in the picture, but if I remember right, they wore US jungle boots, try to buy real ones, not the Chinese copies which break really easily. Cost can be 60 USD - 120 USD or more
