I'd go with the Security Power Armor. It's primarily used either in warfronts or in glitterworlds where there is high crime rate. Nanotech makes the armor material twice as durable as other sets and not only does it have better overshields but also a faster shield recharge rate. The armor also is capable of reducing knockback from both melee and ranged weapons considerably.

@Tirimor
What's the downside then? Longer aiming time and minimal heat protection?

I'd recommend a ghost power armor, aiming takes longer but a greatly increased accuracy. Also increases movement speed by a little bit. Aswell as a good cold and heat resistance, but the armor itself is slightly worse in defence then normal power armor.

@Oskar Potocki No, heat protection would be a must for the armor as glitterworlds mainly use direct energy weapons such as blasters, laser and plasma weaponry. I would think that with all the defensive systems on the armor they had to strip most of the enhanced movement, which is why the armor is more suited for urban warfare and Close Quarters Combat on glitterworlds.

What needs to be put in is the EOD armor set (Explosive Ordinance Disposal). It's iconic and glitterworlds also deal with arson. Explosion resistance with move speed debuff. Seems fair.

What about the military police armor? https://vignette.wikia.nocookie.net/halo/images/8/8d/Vanity_634277045098828387.png/revision/latest?cb=20101212065159
I wonder what would the upside and downdide for this one.

Probably bonuses in social or something as they would be used in wardening and also general combat bonuses. Also, the shocktrooper armor should have it's melee only ability removed and be put onto Samurai instead.

@Tirimor
I have already stated my way on why shocktrooper is melee only.

How about a UNSC Marine armor set i really like the idea and a few people in the comments allready suggested something similar.
Afterall Powerarmors are only for your best soldiers. :P

how about a booster power armor, equipped with mini jet engines to make the wearer go faster, and possibly jumpjets so that the pawn could jump to a specified location if not under a roof, and the armor would provide good cold insulation. the only downside is that it's light, so not too much armor, a bit worse than regular power armor.

Pros:
-Speed boost (armor)
-Jumpjets (armor) (may be hard to implement) (potentially could jump to another spot in the world)
-Targeting AI (helmet) (to estimate the jump distance and direction, could also assist with aiming, decreasing aiming time, or increasing accuracy)
- +0.5 melee/(Ranged?) dodge chance (on both pieces) (Armor, because of jets) (Helmet, because of targeting AI)

Cons:
-Light armor (if it were heavier it would not be able to fly)
-Bad face protection (because of glass visor)

I'll leave you to figure out what you want the values to be. (jump range, how much faster the wearer is, armor value, etc.)

@Oskar Potocki

A possible New Armour set would be All Terrain Marine Gear.
Bonus' would include

Pros:
- consistent move speed in all types of terrain excluding concrete
- Higher dodge chance in cover, allowing them to be superior in combat
- Higher speed values
- Higher Accuracy
- walls and natural features take more damage from firing.
- Higher mining speed (rubble of rock is avoided)

Cons:
- Light armour (allowing quicker movement)
- More time required to aim

Hope this is unique and not redundant, Good job this mod is amazing, will use in next Rimworld Playthrough

A few new armour ideas.

Name: God Slayer
Description: A minimalistic set of armor. Designed with the main purpose of hunting powerful creatures who could destroy the hunter in a single hit, the only survival strategy was not getting hit. The shields are mainly to defend against misceleanous debris and stray shots. The armor plating is mainly to defend the circuitry against pumping into stuff.

Pros:
- high move speed
- powerful shield
- can use ranged with shield
- drop pod like flight (?)
- fatster attacks with all weapons
- more accurate with weapons
- better dodging
- can operate in extreme temperatures
- rather light

cons:
- physical armor near useless
- faster food and rest usage (?)
- difficult to accuire
- low total armor hp
- lower pain tolerance
- slow shields

Name: Survivor of Titan
Description: A set of armor used by the sentinel guards on Titan, after a great incident took place where the only survivors were wearing this armor it went famous. It is well known for it's powerful plating and shields along with allowing the user keep filling their duties with little to no breaks.

Pros:
- super powerful shield
- powerful plating
- can use ranged with shield (?)
- more accurate with weapons
- can operate in extreme temperatures
- immune to toxicity
- immune to pshycic effects (helmet)
- increases carry capacity (only to bring the practical weight of the armor closer to normal)
- heat/shock based areal defense sysytem (non-lethal mainly)
- high total armour hp
- decreases rest and food usage
- increases mood
- increases imminity gain
- decreased aging (?)
- fast shields (?)
- increased foraging (being able to feed the user on caravans for ever)

cons:
- difficult to accuire
- body is very heavy (well over 150kg)
- can't be sent in drop pods
- way slower movement
- less dodges
- slow shields (?)

how about a riot armor
massively buffed defense against blunt
decent defense on other damage
reduced speed
removed abillity to use guns
and adds a buff to meele attacks with a higher chance to induce pain shock rather than inflict real damage.

the backstory could have it as gaurd armor for glitter world supermax jails where it was used to allow the brake up of prison riots without killing prisoners or risking the security.

Some kind of psyfocus light power armor for Royalty DLC please
Maybe not as enhancing as full set of psyfocus clothing, but with decent protection and overshield

a psy focus armor
