Following the minor update 2/10/25, many players seem to not know how to defend their country anymore as defence has been nerfed to the point that troops can actually suffer more losses on fortifications than if they were not on a fort. Taking advantage of this, many others seem to be able to easily penetrate enemy lines and destroy their army, effectively making them an unstoppable force. Here is a tutorial on how to setup your army in such a way so that you can kill your enemies in the same way.
Step 1: Doctrines[]
Before the update static lines and defence was the whole meta. Now? Getting Manoeuvre Warfare is a much better idea. Get Manouevre warfare, and if youre using tanks do Armored Fist, but if you usually use infantry, dont want to stack up war exhaustion and dont want to be in debt the whole game, do Grand Battle Plan, and dont go further than that.
Step 2: Leaders[]
Leaders can give you insane buffs if you get the right ones. After you get your doctrine you should have 350 military power left, and spend it on a ground military leader, preferable one with bunker buster, because this is the modifier that will destroy your enemies entrenched positions. Create a military group, assign the military leader to it, assign all ground troops to it, then press a city, go to units, and on the side assign all ground units recruited to your group, which will automatically set all new units you make to that group. If you dont have bunker buster, set your military spending to max and train all your troops until your leader upgrades, and try to get it. If you dont get it, then at least you have some pretty good attack on your leader. If you have enough political power try to get a chief of army that will increase your armies strength over time.
Step 3: Training[]
If you have enough income, always train your troops. It will prepare your troops for combat, as well as upgrading your leader and getting you some good attack and defence bonuses. Make sure that before going into war your troops are trained for combat in the biome or terrain you will be fighting in to inflict maximum damage.
Tips[]
Before going into war make sure your military spending is up to the max and that your troops are at maximum readiness.
Make sure that if an enemy is approaching your entrenched troops that you move them so that you can counter your enemy also using manouevre warfare.
