Glad to see that the Ultimate Force thread has been tidied up, it looks great

Just wanted to add a couple of guns to the list.

In the episode "The list" the terrorist operative is given a Walther P99 to use. I think it is one of the second gen ones, without the fugly as hell finger-guard.

In episode 1.2 with the AW-50 & the anti-globalist protestors, the black woman uses a stainless or nickel framed IMI Jericho.

In 3.1 (I think), at Ed's funeral the squaddies who fire the 21 shots are using L98A1 training rifles, not the standard issue L85A1's. You can tell this because they manually cock after each shot, which you would have to do with the semi-auto L85's. However in the other funeral they do use regular L85A1's in semi.
The L98's are used by cadets and come in two versions; one kind have the gas-system removed and are therefore bolt-action rifles, used only on the range; the others have all their internals welded together so they are inoperable and are used whilst the cadets are running about so they don't slot each other.

And as a last point; in the last episode of season two when Henno and the officer are fighting through the building (a couple of mins before Henno frags the officer). Henno reloads his M16, when he pulls the charging handle the extractor fails and a round jams forcing the charging handle to stick out by about four inches. I dunno if you'd want to stick a screen-cap up there of it but in the Punisher 2004 article someone pointed out all the stovepipes.
