Failed to invade cuba 3 times now
Went as Canada communist. I have mostly infantry, mech infantry, light tanks, and 4 marines.

I got no air support due to airfield...being pretty far away from Cuba. Got no carrier or heavy bombard support. I tried to invade from multiple directions but the enemy is really in-trench on the island. Manage to take two areas but got pushed back again.

Most of the division's are 20 and some 40 width. And my next year even built one carrier is like 1947.

A couple things:

You didn't take any ports, so any divisions you land are going to quickly run out of supplies.
You want to target ports as a #1 priority because without them you'll hardly be able to push in.
If you really must, you can build a port where you land, but this will take about a month and leaves you very vulnerable. (You can also build land forts to buy yourself some extra time, so long as the tile isn't in combat)

Shore bombardment is key if you don't have any air support. If you're just fighting small countries with no navy/airforce, you can spam out some cheap heavy cruisers with nothing but guns to help.

You're invading with tanks and mobile infantry, which are awful divisions to initially invade with. They receive a massive attack malus that e.g Marine divisions don't. Make a few pure inf/Marine divisions to do the initial landings, after that you can roll your tanks in.

Your generals don't have a Field Marshall. They don't add all that much, but every bit helps. Even a few % for attack or supply reduction can make the difference.



If you were to try again, I'd recommend:
Building a few cheap ships to get some shore bombardment, you can spam out early cruisers (both light and heavy) to help.

Only naval invading in tiles that have ports, or are immediately next to ports.

Using a Field Marshall from the start you can grind up some key traits (like supply use reduction which helps with naval invasions)

Making a few specialized marine divisions/infantry divisions (pure inf/marine, engineer support, arty support) to help land, after that you can do whatever.

If you really want to cheese it, you can spam out a bunch of 2 width infantry divisions to raise your special forces cap.

Or just build a floating harbour and use that

Based on the lack of the LaR ops tab, I was assuming the OP didn't have every DLC.

But, you're right, if you have NSB, floating harbors can give you the time needed to push/capture a harbor/build your own.

The next ship to build wont be till like 6 years XD.

ooo, I would have thought tanks would be useful due to the high breakthrough.

Field Marshals? I don't think I ever used one before.

You don't have to build a big capital ship. (Also if it's taking 6 years odds are you're doing something wrong, either assign more dockyards or get all the resources needed)
Heavy Cruisers are much, much cheaper than Battleships or Carriers. Much better bang for your buck.

Tanks are useful, but not for the initial naval invasion. Almost all divisions get a malus (debuff) when preforming a naval invasion. This is one of the things that make Marine infantry so good for invasions and why engineer divisions are so important. Tanks get a much higher debuff than infantry.

https://hoi4.paradoxwikis.com/Terrain#Unit-specific_adjusters

Per division, Infantry have a 0% modifier, line artillery has a -40% modifier, Motorized Inf has a -20% modifier, Light Tanks have a -40% modifier, Medium Tanks have a -80% modifier. In short, pure inf isn't getting seriously debuffed, but tanks/mobile inf or arty divisions are getting hit hard. You can click on the naval invasion bubble and hover over your divisions to see what the % debuff is.

Marines actually get a 50% buff[//i] for naval invasions, helping offset the serious penalty, combined with an engineer company (+25% attack) you can push hard with good divisions. Remember to research your special forces (+org and supply grace really help here).


For Field Marshals, you just select the generals and right click the blank '+' profile to their left and it'll group them. You may need (or at least want) to promote a general to FM depending on the country you play. They provide additional bonuses to the troops under their command, increasing the usual stats, attack/defense and increasing planning/planning speed while reducing supply consumption.

I didn't focus on navy (mostly tanks,mech). I only got 2 dry docks, trying to build more. Yea I see where it all went wrong. An hour ago, send another invasion with the 40 naval invasion tech, And... it's another mess lol

Gunna go ahead and redo all my stuff and wait another year o two before attacking.

Went again and failed once more. Kinda went a little better this time but the lads eventually had to retreat. Lost another 200k + manpower and 10 divisions wiped out XD

The AI`s last stand spam has made naval invasions alot harder. I solved it by navalinvading the same port with several orders. 2divisions in an invade order and 5 orders works wonders for me. But stil fails if AI has lots of entrenched troops.
