Here are any kills that were partially obscured and/or were confirmed later on but not directly seen on-screen.
Second Drazen Guard
This man was armed with an Uzi and likely died from the impact of Bauer's van hitting the booth he was in.
This man was later confirmed by the roster seen at the beginning of Day 9 and was likely killed during the brief scene where Bauer shoots at some men off-screen prior to going after both Andre and Victor Drazen.
Cheng's oil rig guard
This man was one of the men who went and attacked Bauer prior to being either shot or blown up by the explosions Bauer caused.
LIVE ANOTHER DAY
Cheng Zhi's six unnamed mercenaries
In-between the dock raids and jump to Audrey Raines' murder segment, there were six men killed by Bauer and/or shared with Belcheck. They were seen on Cheng's thermal satellite imaging feed of his departing ship. I'm also pretty sure that Cheng's thug who Chloe hit with a pipe earlier was one of these guys unless he randomly decided to take a pay cut and walk out of the picture earlier than expected (unlikely).
