In Diplomacy is Not an Option, choosing the right units can mean the difference between victory and a crushing defeat.
As waves of enemies flood toward your settlement, each unit’s role becomes crucial for both defense and offense.
From basic infantry to powerful ranged units, knowing which units are best suited for various scenarios will give you an edge in surviving the relentless onslaught.
Let’s dive into the best units in Diplomacy is Not an Option and how to use them effectively.

The Basic Infantry: Your Backbone
At the heart of your army is the standard infantry unit. While they may not be flashy or particularly powerful, infantry are crucial in holding the line.
Their primary role is to act as a buffer, soaking up damage while your more specialized units do the heavy lifting.
Swordsmen
Swordsmen are your bread and butter, the most basic melee unit you’ll have access to early in the game.
They’re cheap, quick to produce, and can hold off small waves of enemies. Though they don’t have high damage output or health, they can swarm enemies with numbers and buy you precious time to build up stronger defenses.
Use swordsmen in the early stages of the game to protect your structures while you gather resources for better units.
However, don’t rely on them too heavily in the late game, as they’ll get overwhelmed by stronger enemy forces.
Spearmen
Spearmen are a slight upgrade from swordsmen, offering better range with their attacks. They are effective against enemy cavalry and can hold the line better than swordsmen in certain situations.
When faced with mounted enemies or units that try to bypass your defenses, spearmen are your go-to choice for defense.
The Power of Archers
Archers are one of the most valuable units in Diplomacy is Not an Option.
Their ranged attacks allow them to deal damage before enemies even reach your defenses, making them essential for both offense and defense.
Archers
Basic archers can be stationed on towers or walls to shoot down approaching enemies from a distance. They excel in thinning out enemy ranks before your melee units engage in combat. The key to using archers effectively is positioning.
Keep them behind your infantry or high up on towers so they can shoot without being vulnerable to melee attacks.
Since archers have relatively low health, never leave them unprotected. Always pair them with melee units or defensive structures to maximize their potential.
As your army grows, focusing on building up a large force of archers will give you a powerful advantage in the later stages of the game.
Siege Units: Breaking Through Enemy Lines
As you progress, you’ll encounter situations where basic units won’t be enough to deal with larger threats. This is where siege units come into play.
These units specialize in breaking down enemy structures and can cause mass destruction to large groups of enemies.
Catapults
Catapults are fantastic at dealing heavy damage to enemy structures and clustered enemy forces. Their long range and area-of-effect damage make them a key part of any strong army.
However, catapults are slow to move and reload, meaning they need to be well-protected by other units while they operate.
Use catapults to take down large enemy structures or to create gaps in enemy defenses.
But be aware of their vulnerability to fast-moving melee units that can destroy them if left unguarded.
Ballista
The ballista is another powerful siege unit, perfect for targeting large enemies or heavily fortified structures. While not as destructive as catapults in terms of area damage, ballistae deal more concentrated damage, making them ideal for precise attacks on specific targets.
Position your ballistae behind your main army, and let them chip away at high-priority targets from a distance.
Like catapults, they require protection to avoid being overrun.
Specialized Units: Magic and Healing
Beyond your basic infantry and siege units, Diplomacy is Not an Option offers more specialized units that can turn the tide of battle when used correctly.
Mages
Mages are one of the most versatile and deadly units in the game.
Their ability to cast devastating spells allows you to destroy large groups of enemies or turn the tide in battle when things seem bleak.
However, they come with a high resource cost and are limited in numbers, making them a unit you should deploy strategically.
Use mages to deal with powerful enemy forces or to decimate clustered enemies before they reach your base. Their spells are particularly useful in defensive situations where your walls or structures are under threat.
Healers
While combat units often steal the spotlight, healers are invaluable for keeping your army in the fight longer.
They can heal injured units, allowing them to stay on the front lines and continue fighting without the need for reinforcements.
Position healers behind your infantry or archers to support your units as they engage with the enemy. Keeping a few healers in your army can make a significant difference during long, drawn-out battles.

Conclusion to the Best Units in Diplomacy is Not an Option
In Diplomacy is Not an Option, mastering your units and knowing when to deploy them is the key to success. While swordsmen and archers form the core of your army, specialized units like catapults, mages, and healers will give you the upper hand in more challenging battles.
By using the right combination of units, defending your settlement and expanding your territory becomes much more manageable.
So, gather your troops, fortify your defenses, and lead your kingdom to victory!
