AI Use of SPeciality Units

I have long been frustrated with the seeming lack of utility of the two main "speciality units" - the marine and the paratrooper. The marine comes so late in the game it hardly seems useful (marines against mech inf does not produce winning amphib battles -- paratroopers with an 8 defense do not survive behind enemy lines when the enemy has railroaded territory and modern armour or even tanks).

I recently completed a game (Babylonians, Monarch, Standard, Continents, 8 Civs, Temperate, 4 Billion Years, v1.21f) during which my initial goal was to test several late game mods I wanted to experiment with, so I disabled Diplomatic, Cultural, and SS victories to avoid an early exit (yeah, I know, Babs but no cultural victory???). Of principal interest to this thread are the relatively minor mods I made to marines and paratroopers, and the greater mods I made to cruise missles and naval units (after lurking here and elesewhere and soaking up others' knowledge and ideas ). I don't know if this is random, or a result of the mod, but the AI seemed to take great advantage of my SOME of my mods.

Briefly, the mods:

cruise missle range to 4 tiles
submarines carry 4 foot soldiers (with AI strat "Naval Transport" flagged)
Nuclear subs carry 4 missles (cruise or tactical nuke)
Aegis carry 2 crusie missles (not nukes)
BB carry 1 cruise missle (not nukes)
paratroopers 7.9.1 (one production cost increase)
marines 9.7.1 (one production cost increase)
helicopters transport up to 4 foot soldiers

The argument for cruise missle mods and helo mods can be found on numerous threads. The idea with subs and foot soldiers is that subs can insert small special ops teams well behind enemy lines. The idea behind marines and paratroopers is that the should have overall/combined ADM of infantry, but higher cost given their special abilities.

What I found in gameplay with respect to one mod surprised (and pleased) me!


The AI INTELLIGENTLY used paratroopers. In the late game, in an effort to whittle down a larger and more advanced civ (Joan) I set about denying her any aluminum (and therefore modern armour). Even though Joan had the resources to make tanks, she spent a fair amount of production effort on paratroopers. Okay, I thought -- 'Stupid Joan, takes you one turn to pump paratroopers, but 2 turns to pump tanks, so you pump paratroopers.' BUT, Joan proceeded to airdrop paratroopers well behind my advancing lines, landing on both luxury and strategic resources, and even on a choke point with multiple paratroopers to hold the point (which happened to be undefended and have a fortress on it). At the same time, Joan was inserting 3 or 4 paratroopers at a time on MY continent via submarines -- I didn't have the coast ringed with Aegis and obviously didn't see any transports coming -- lo and behold, all of a sudden 4 paratroopers on home soil near weakly defended cities).

Now, I have NEVER before seen the AI use marines or paratroopers intelligently (and I wish Joan had been inserting marines onto my continent rather than pts, or, better yet, had pounded a coastal city with multiple cruise missles from a nuclear sub to soften defenses and then taken the city with marines off-loading from a sub, as I did against the AI ), and have rarely seen the AI use marines or paratroopers at all except where a reource deficiency deines them the ability to produce tanks, etc.; but I was very happy to see Joan using paratroopers to their full advantage as deep penetration infantry. Even with my mods, I still have never seen the AI use marines or helicopters intelligently (even though Joan built, but never used, several helos).

Has anyone seen the AI use paratroopers intelligently? Has anyone seen the Ai use marines intellignetly? I've only played 5 or 6 games at Monarch (most of my games have been on Regent) and don't know whether Joan's smart use of paratroopers has to do with the higher difficulty level, my own mods, or both.

All feedback appreciated .

In a recent game I played as the Indians, the Aztecs declared war on me in a pact with the Chinese. In the very same turn an Aztec transporter turned up full of marines straight into my least defended coastal city.

It was the only time I have ever seen the AI use marines tho I have seen them use paras occasionally to take out resources.

yes that they attack xith marines comes very rare

In my games, the AI tends to use both marines and paratroopers as some sort of offensive infantry. It does not use any of the special abilities, but merely sends the units slowly by land to get slaughtered, as if they were ordinary troops.

. . . I've been waiting for an AI amphib assualt for months.

Can you share details on your game? (i.e., was it modded in any way, world size, map feature, difficulty level, etc.) And did the Aztecs continue to use amphib assaults or was it just the one time?

I really think that if the AI would learn to use the specialty infantry units more, it would impose on the human player a whole new tactical (even strategic!) set of challenges.

Anyone else seeing AI amphibious assaults?

Thanks, all.

I did get one amphibious assault from the AI on a weekly depended city, caught me utterly by surprise. In my games I also see a fair number of marines used as offensive infantry. However, this may be because I have substantially upped the cost of Tanks and Armor, forcing the use artillery and bombardment units for the majority of the attack force. And instead putting the tanks more into the support role that they are supposed to be.

Sounds Interesting!! What values did you use??

The game I was playing was a huge map with 16 civs using the 1.21f patch.

The game was not modded in anyway.

That was the only time they had the chance to do it as very quickly the Chinese overwhelmed me and I retired so I didnt get the chance to see if they would do it again.

I always play on huge maps with 16 civs with random everything unless its GOTM.

Oh yeah and it was only on warlord!
