Authors note: much of these ships and equipment come from the halo fanon and my own mind

materials:

Titanium a4: An improvement on the titanium a3 a4 is superior to the titanium a3 and a in every way capable of taking a serious pounding from even covenant plasma without boiling away instantly this is used in everything from ships to ground based installations

individual equipment

m75 marine bdu

the m75 is a replacement for the aging m52b armor the look of the armor is shared with the cross branch bdu used by marines on reach with heavy armor plates over soft armor layer along with a layer of heat dispersion gel and helmets with a polarised visor,hud,an internally built filter to filter out toxic elements and additional equipment to face the elements alongside various comms units integrated with their neural implants have become standard the armor plates themeselves are made of a derivative of the famous titanium a4

and is able to take 4 plasma shots before failure adding to all this, the joints in the armor have carbon fibre nanotubes which enhance a marines strength and reduces the pressure of the armor on the marine. the marine is also equiped with the m30 personal shield generator this shield is capable of taking 2 plasma shots before failing and regenerates quite slowly ( these guys look like halo reach marines ) and it can be sealed to survive in space for 20min

m100 ODST armour

the armour worn by ODST's when jumping feet first into hell the armour has every thing that the marine bdu has and more. a better armour configuration allows the armour itself to take 5-6 plasma shots before failing ODST also recieve basic strength and speed augmentations the m50 shield generator can take 4-5 plasma shots before failing

m45 army bdu

this is basically marine armor but without the visor filter or shield or sealing capability (army rangers have these)

ma40b2 AR

the ma40b2 is an upgrade to the venerable army ma37 and ma40. this is the standard AR of the unsc replacing the ma5 series with a 36 round magazine firing 7.6251mm rounds with improved propellant giving it more power as a base and have electro magnetic coils along the length of the barrel propelling the round at extreme speeds with great penetrating power and good accuracy being able to drop an elites minors shields in 5 or 6 shots it is very reliable but the coils require some maintanence but the gun can be fired without them albeit with less power

m400 DMR

the m400 is a combination of the br55 and the m392 DMR while sharing the look of the latter it has the burst fire mode of the the br with a 32 round mag the DMR also has the same coils as the ma40b2 and drops an elite minors shields in 2 to 3 shots but it does have a bit of recoil

the m300 SAW

the primary squad automatic weapon of the unsc equiped with the same coils as the previous weapons it has a fire rate of 950 rounds per minute this weapon was feared by both covenant and insurrectionists

srs 99mk2 AM riflethe most heavily used sniper rifle of the unsc the srs 99mk2 anti material rifle is an absolute beast of a weapon an improvement of the original srs99 the mk2 has the previously mentioned em coils integrated capable of killing all types of covenant infantry from over a kilometre distance the sniper is a truly powerful weapon

aa39 automatic shotgun

using a 30 round drum it fires 8-12 guage rounds at nearly 400 rounds per minute capable of ripping enemy targets to shreds at close range the aa39 makes even the brutes think twice before charging headlong into battle various underbarrel grenade and flame thrower attachments

Vehicles

M700 hound AFV

The hound is an interesting vehicle

Armed with a 30 millimetre autocannon and 2 light machine guns and either a 40mm grenade launcher or a irkut ATGM that can wreck a wraith tank in 1 or maybe 2 shots and covered in thick titanium A4 supposed to support tanks has a shield generator along with an aps system that defends it from rockets drones and even occasionally tank shells

M400 tiger

it is a fully enclosed modular apc with a 14.5mm heavy machine gun on a rcws system complete with thick titanium armour,energy shields and an aps system it is meant to be a troop carrier carrying 20 marines or even heavy troops like spartants

M808C3 SCORPION MBT

the c3 scorpion has multiple advantages over its predecessors many of the weak spots and points have been fixed along with new systems better sensors a superior 120mm gun with apfsds rounds coaxial mounted machine gun thicker titanium a4 armor the gun is now able to elevate almost 90 degrees to fire atgms at flying targets a superior loading system able to fire every 4 seconds and energy shielding all alongside aps a heavier version is in service with the army

AUTHORS NOTE
this is getting way too long so next chapter will be command and battlecruiser, carriers , battleships and dreadnoughts
again most of these ships are taken from the halo fanon with my own flair added to them be back with you in a bit
