This is Blue Box Toys / Elite Force Raider
So back then, BBI would generally release two or three figures in a "wave" at once. Here they reuse the Trident rifle to make the Raider rifle. Except it's black and has suppressor and has a tac light, other than that, it's the same. The Sig Sauer is close to the same basic design, except it has an extended threaded barrel for a suppressor, and an underside laser/light to attach to the pistol's rail system. The SAT COM IIRC was repeat from a previous set. Uses the same boots as Trident but the interesting twist here is the civilian oriented clothing, somewhat, and the 5.11 low profile vest.
When this was coming out, there was a lot more activity to Private Military Contractors overseas for close protection. This was obviously post 9/11 in the world spectrum. This set was popular and it was not at the same time. Lots of hobbyists wanted civilian gear or something close to it. But honestly, and this was noted by some dealers who spoke in the forums at the time, this kind of stuff just didn't sell as well as the traditional military.
A dealer I knew sold me a case of 6 of these Raiders for 18 per set. No tax, free shipping. That's not even near his cost basis by any measure. This was after a while, they couldn't sell, so he said to me in private and in email, and he needed to just unload them and didn't want to bother parting them out. ( The parts market for these wasn't robust) BBI released another version of this figure again, with some small changes, to try to recoup their investment on the tooling/molds, etc, etc.
My guess as to what happened? The economy overall was not in a great place. Not yet into the 2008/2009 type death spiral that happened, but the Dot Com Boom was not holding the same traction. Also the big brands them like DML and BBI were facing changes in the size of their edition runs. Making fewer figures in a run meant higher prices. Higher prices would drive out some collectors. It would also impact the loose parts market. The headsculpt here also wasn't very good, and back then, a really great headsculpt was a major driver in interest in a set. This was before the advent of so many licensed figures, so to get a good Brad Pitt or Tom Cruise sculpt or something like that was much harder to find than today. Back then, there was more clamoring by some for foreign figures, but they just didn't sell as well. Now, as the hobby has progressed and edition runs are smaller, you'll see more foreign figures made.
This was a good set, just unfortunately timed. Had it come out a year and a half before, maybe the appeal would be different. Which was the other issue that became apparent. Releasing a set at it's time and maybe not 6 months earlier could have a dramatic impact on it's interest. The big hobby drivers back then were Saving Private Ryan / Band Of Brother and Black Hawk Down. The reignited interest in mainstream war films created a context of interest for the entire 1/6th military side of hobby.
Raider was an interesting set. The great deal I got on him was great for me as an individual collector, but bode poorly as a trend for BBI / Elite Force Modern Military as a sustainable line at the time. In effect, part of the complexity was the death of the "budget" oriented figure designed for brick and mortar sale. ( Toys R Us was dying as a storefront business model back then too) As people shed the hobby, they liquidated their collections onto the secondary market, again, creating some good deals for remaining hobbyists, but all but ensuring smaller future edition runs that would define prices points that would keep creeping up.
Our hobby only exists today because of good timing. The advent of the widespread use of the internet. ECommerce as the new collecting standard. Speed of information. But those same factors helped to turn this hobby into something more and more niche. You are given. Then you have things taken away. The nature of things.
I genuinely love this hobby. But I also understand that there are some folks who got into it later and never got to see the old days, when things were different, and for that, I think there is a type of loss for them. The entire concept of FOMO wasn't hard set yet in so many collectors. The same degree of instant gratification wasn't as common. It was different. Not better, not worse, just different.
