Most tier lists are popularity contests. This one isn't. We rank by defensible reading of stats + map geometry, not by fan poll or vibe. Every position is justified with math; you can disagree and we'll show you the numbers.

A unit's tier depends on the map, the mode, the team composition, and the player's skill. A "tier list" that gives one global ranking is wrong by definition — a tier list that breaks down by context is useful.
What this list is:
What this list is not:
Where each unit's polygon is biggest = where the class wins. The Sniper's polygon is the most asymmetric (one axis dominant); Enforcer covers the largest total area.
Each unit's tier varies across the three maps. There is no "best unit" globally — only "best unit on this map."
Strong on 2 of 3 maps — the only unit with this much consistent ceiling. 320 resistance + 60-round EnfExt210 means Enforcer wins extended trades at any range below 30 meters. On DMArena, where engagement range is 5-15m, this is map-defining. On Upper Platforms, the same equation makes Enforcer the best capture-point anchor in the roster. The 6.5 speed weakness only matters on Administration HQ's long lanes, where Enforcer is "OK" rather than dominant.
Strong on 1 map, poor on 1, OK on 1 — the highest variance unit. On Administration HQ, TG-87's 152 damage at 30-50m range is a one-shot threat to every class' headshot HP. The map's long atrium sight lines were designed for this. On DMArena, the same TG-87's 2-round magazine + bolt-action delay makes it a liability against close-range Enforcer / Assault. Sniper is the unit you pick when the map is right; it's the worst unit you can pick when the map is wrong.
Solid on all 3 maps, dominant on none. 250 resistance + 30-round Rifle0 means Assault never gets shut down by a hard counter — but it also never bullies a specific matchup. Pick Assault when you don't know what the enemy team will field, or when your team comp already has 2-3 specialists and needs a flexible filler. On Upper Platforms it's strong because the 30-round magazine handles capture-point pressure; on DMArena and Administration HQ it's "OK" because Enforcer + Sniper do the specific jobs better.
Strong on 1 map, OK on 1, poor on 1 — similar variance to Sniper but with a different shape. Infiltrator is the only class with non-Grenade tech (Xray + Cloak), and the value of those abilities depends entirely on map geometry. On Upper Platforms, multi-level platforms create flank routes that Cloak makes free; Xray reveals enemy positions through walls. On Administration HQ, Cloak supports flanking around Sniper sight lines. On DMArena, both abilities are functionally useless — tight corridors don't have flank routes, and audible engagement range nullifies Xray's intel value.
Pick in this order:
