The Mark VIII Tactical Operations Suit is a standard Fourth Echelon operations suit for field operatives. It first appears in Tom Clancy's Splinter Cell: Blacklist and it is the first suit available to the player. Unlike previous suit types, the Mk VIII suit can be customized by the player with different camouflage types for different environments. Both Sam Fisher and Isaac Briggs use the Mk VIII in Splinter Cell: Blacklist during The Engineer's Blacklist attack. It is the first customizable Splinter Cell suit (not counting the 3E Eclipse, which only provided Armor, Gadget, and Ammunition Upgrades in Conviction without any changes in physical appearance) and comes with many modifications for Stealth and Assault purposes, in which both Sam and Isaac take advantage of to suit their needs.
