Design a Kowloonese Marine suit.

[Cannonshop]

I need a standard suit design, it needs to be in the range of light to medium, it needs improved sensors, magnetic clamps, improved armored gloves, and a certain level of modularity to cover a wide range of environments (deep space to deep water).

It also needs decent ground speed (either fast running or jumping).

and a flexible assortment of ways to inflict pain and suffering upon enemy units ranging from traditional battlefields, to boarding actions in space.

good luck.

What is "Improved armored gloves"? There isn't one. You mean something more than just armored gloves?

EDIT Also, the level of requirements is... excessive, to borderline impossible. They can be covered if a series of suits is allowed (let's assume suit to suit conversion is doable if not truly modular). The impossible part is that while a normal suit can work in space, underwater BA require UMUs and those require Clan-tech AND aren't modular systems.
That said, throwing away underwater requirement (or leaving that to a separate suit) is reasonably intriguing challenge. But the results are likely sub-par.

Anyway, initial proposal.
This one works in space if not great because is lacks space operations adaptation package (that masses 100 kg which is problematic), as noted underwater capability is no-go.

175kg, medium IS chassis
150kg, 3 jump jets
400kg, 8 points standard armor
15kg, battle claw, left arm
0kg, armored glove, right arm
30kg, magnetic clamps, torso
65kg, improved sensors, torso
5kg, searchlight, left arm
10kg, modular weapon mount, right arm
---150kg, 2 slot MWM capacity

Armament options (fit into slot/mass limit):
Flamer
MRM-1, 4 shots
MRM-1-OS One Shot
MRM-2-OS One Shot
SRM-1, 4 shots
SRM-1-OS One Shot
SRM-2-OS One Shot
Machine gun (any)
Firedrake needler
Gauss rifle (David, Tsunami, Grand Mauler)
Grenade Launcher (heavy, micro)

For space operations adaptation installation, armor could be reduced to 6 points though this is really too little for safe combat use. Removing 1 point of armor and 50kg weapon capacity is an option, but there is limited number of useful weapons at 100kg (and no energy weapons). Presumably stripping magnetic clamps and improved sensors is not an option.
