It's a trap. You see the massive shoulders, the power armor, and the Boltgun that looks like it could punch through a brick wall, and you think "I'm invincible." Then you put your Space Marine kill team on the table, move them into the open like the demigods they are in the novels, and get absolutely shredded by a handful of Pathfinders or a lucky Gene-stealer. It’s a humbling experience. Most players coming from "Big Warhammer" (40,000) struggle with the transition because the scale changes everything. In the grim darkness of the far future, being a super-soldier is great, but in a skirmish game, being a target is a death sentence.
The reality of the current edition of Kill Team is that Space Marines—specifically the "Compendium" versions—have been largely eclipsed by bespoke teams. If you’re still running a basic tactical squad, you’re playing on hard mode. The game has evolved. We’re in an era of specialized operatives, complex "Plloys," and tactical ploys that make a standard Intercessor look like a paperweight.

The False Promise of Power Armor
Let's be real for a second. The 3+ save is the biggest lie in the game. It feels safe. It feels like you can take a hit. But with the prevalence of AP (Armor Penetration) and lethal critical hits in the modern meta, that armor is more like a suggestion than a guarantee. When you're playing a Space Marine kill team, you usually only have six bodies on the board. Six. That’s it. Your opponent might have ten, twelve, or even fourteen models.
This creates a massive "action economy" deficit. While you’re moving one guy to secure an objective, your opponent is moving three pieces to flank you, chip away at your health, and score secondary points. Every single loss you take is roughly 17% of your total fighting force. If a plasma gun melts one of your brothers in Turning Point 1, you’re basically playing a different game than the one you signed up for. You have to play cagey. It feels "un-fluffy" to hide a seven-foot-tall tank behind a crumbling wall, but if you don't, you lose.
The Rise of the Bespoke Angels
If you want to actually win games, you have to look at the specialized teams. Games Workshop moved away from the "choose your own adventure" style of the early Compendium and toward fixed, highly specialized rosters.
- Intercession Squad: This is the gold standard for many. It’s free (available via Warhammer Community), and it’s arguably the most balanced way to play Marines. You get to mix Intercessors and Assault Intercessors. It sounds simple, but the "Chapter Tactics" mechanic lets you customize your team's DNA. Want to be harder to kill? Take Hardy. Want to be a menace in melee? Dueller is your friend.
- Phobos Strike Team: This is for the players who like to pull their hair out. It’s a high-skill-ceiling team. You’re using Vanguard Marines—Reivers, Infiltrators, and Incursors. You aren't winning by out-shooting the enemy in a fair fight. You’re winning by using "Vanguard Medals," planting mines, and using smoke grenades to manipulate line-of-sight. It’s a psychological game.
- Strike Force Justian: Think of this as the "easy to learn, hard to master" entry point. It’s a fixed team of seven specific characters. No roster building, no gear choices. Just pure tactics.
Mastering the Turning Point 1 "Dance"
Most Space Marine kill team players lose the game in the first five minutes. They get aggressive. They see an objective in the middle of the board and they want it. Don't.
Space Marines thrive on the "Retaliation Strategy." Because you have fewer activations, you will almost always be the last person to move your important pieces. Use this. Let your opponent commit their squishy models to the board. Let them reveal where their snipers are. You spend your first few activations moving into "Conceal" positions, hovering just outside of threat ranges. Then, with your final two or three activations, you strike.
A single Boltgun shot from an Intercessor with the Bolter Discipline ploy allows you to shoot twice. That is your equalizer. If you can delete two enemy models at the end of Turning Point 1 while losing none of your own, you’ve effectively neutralized their numbers advantage. It’s about surgical strikes, not a frontal assault.
Why the Bolter Isn't Always Your Best Friend
We love the Bolter. It’s iconic. But in Kill Team, it’s often underwhelming against high-health targets or anything with a decent save. This is why the "Gunner" and "Heavy Gunner" slots are the most important part of your roster.
If you aren't bringing a Plasma Gun, you're asking to lose. Plasma is the great equalizer. It deals 5/6 damage with AP1 (or AP2 if overcharged). That kills almost any non-leader model in the game in one or two hits. Then you have the Frag and Krak grenades. Honestly, a well-placed Krak grenade is often more terrifying than a whole squad of Scouts. It’s a one-use delete button. You have to be precious with it.
The Verticality Trap
One thing people forget is that Kill Team is a 3D game. Space Marines are heavy. They aren't particularly fast. If you’re playing on a board with lots of "Vantage Points," you need to be extremely careful. A sniper on a roof can see over your cover and ignore your "Conceal" order.
However, you can use this too. A Phobos Marksman on a vantage point with a "Track Target" ability can lock down half the board. It’s about area denial. You don't even have to pull the trigger to be effective; the mere threat of a Marine with a clear line of sight is often enough to force an opponent to take the long way around, wasting their precious actions.
Tactical Ploys You’re Ignoring
- Transhuman Physiology: This is the "Oh no you don't" button. Turning a failed save into a success or a normal hit into a fail can swing a game. But you only have so many Command Points (CP). Beginners blow their CP on re-rolling dice. Professionals save it for Transhuman or And They Shall Know No Fear.
- Shock Assault: If you’re playing Assault Intercessors, this is your bread and butter. Fighting twice in one activation is disgusting. It allows one Marine to clear a point of two smaller enemies in a single turn.
The Mental Game: Elite vs. Horde
Playing a Space Marine kill team is a lesson in patience. You will be out-maneuvered. You will be out-pointed on the primary mission for the first two turns. That’s okay. The Marine game is a game of attrition. You are trying to break the enemy’s back so that by Turning Point 3 and 4, they have nothing left to hold the ground.

I’ve seen games where a single Intercessor Sergeant held off four Orks just by being annoying and using the "Parry" mechanic effectively. You have to know when to strike and when to just stand there and be an obstacle. Marines are "bulky" in terms of their base size and their presence. Use your physical bases to block doorways and narrow corridors. Force your opponent to deal with your armor.
Strategic Nuance and Chapter Selection
While the game rules for "Intercession Squad" give you generic traits, the "feel" of your team should dictate your playstyle. If you’re playing as Black Templars, you’re looking for that close-quarters aggression. If you’re Raven Guard, you’re likely using the Phobos rules to stay hidden.
The most successful players I know don't just pick the "best" traits; they pick the ones that shore up their weaknesses. If you struggle with movement, take something that buffs your dash or charge distance. If you hate dying to chip damage, take the trait that lets you ignore the first point of damage from every attack. It's about building a toolkit, not just a stat block.
Equipment Choices: Don't Get Fancy
Keep it simple. Combat Blades, Purity Seals, and Grenades.
Purity Seals are essentially a luck insurance policy. In a game where every roll matters, being able to flip a crucial fail to a success once per game is worth its weight in gold. Don't bother with the over-complicated gear unless you have a very specific plan. You want consistency. Marines are the "reliable" faction; lean into that reliability.
Actionable Next Steps for Your Next Match
To stop getting tabled and start winning with your Marines, change your preparation.
- Drop the Compendium: If you're still using the "Space Marine" entry from the original 2021 book, stop. Download the Intercession Squad rules from Warhammer Community. They are better, more modern, and more competitive.
- Focus on "Secondaries": Marines struggle with the primary mission because they can't be everywhere at once. Pick Tac Ops (secondary objectives) that reward you for killing things or being in specific spots, rather than things that require you to interact with six different objects.
- Abuse the "Shoot Twice" Mechanic: If you have an operative with a Bolt weapon and you haven't used Bolter Discipline, you are leaving damage on the table. Plan your turns around making sure your best shooters can fire twice.
- Practice the "Conceal" Shuffle: Learn exactly how "Obscuring" and "Cover" work. You should spend 70% of your first two turns with "Conceal" orders, only switching to "Engage" when you are guaranteed a kill.
- Watch the Professionals: Look up tournament results from events like the Las Vegas Open or AdeptiCon. See how the top-tier Phobos or Intercession players navigate the board. You'll notice they rarely take "fair" fights.
Space Marines are the face of the franchise for a reason. They are iconic, brutal, and forgiving of some tactical errors due to their high wounds. But to win in the tight, claustrophobic corridors of Kill Team, you have to stop thinking like a commander of armies and start thinking like a predator. Every shot must count. Every movement must be calculated. The Emperor protects, but a good piece of heavy cover protects a lot better.
