Shieldbearer

"'Get behind me, I've got this.' - A new Shieldbearer about to be vapourized."The Shieldbearer is the Soldier equivalent of a trench- an unyielding bulwark that shields those behind them.

Interceptor
When you take this Subclass, you immediately gain the Interception Fighting Style and may utilize it without wielding a Shield or Melee Weapon. If you already have this Fighting Style, you may instead choose another. You also gain Expertise in the Athletics Skill if you have it- if not, you gain Proficiency in the Athletics Skill instead.

Cover Deployment
You gain the ability to prepare deployable half cover. At the end of a Long Rest, you prepare a number of sets of deployable cover equal to 1 + your Proficiency Modifier. You may deploy the cover in combat as a Bonus Action (if an another person deploys your cover it requires a full Action), and it is a 15ft long straight piece of Half Cover. The Half Cover has 50 Hit Points and is hit if the target is missed by 3 or less on the d20 roll. Once deployed, moving the cover around reduces you to half speed.

Never Fall Back
Whilst you are in cover against an enemy, you may use your Reaction to make an Opportunity Attack whenever they enter or move within 30ft of you.

Greater Interception
You gain the ability to deflect blows at close allies even more effectively than before. When a character within 5ft of you is targeted by an attack, you may expend your Reaction to protect them. Roll a d8 and add the number to their AC. If the strike still hits, they have Resistance to all the Damage types of the strike except for Plasma Damage. You may do this a number of times equal to 1 + your Constitution Modifier (Minimum of 1), resetting on completing a Long Rest.

Cover Expansion
When you use your Cover Deployment ability, your cover is now 25ft long as opposed to 15ft. you may now also shape it how you wish instead of it being a straight line. The Cover's Hit Points also increase to 100.

Keep Your Head Down!
You may now utilize your Interception and Greater Interception Reactions to anyone sharing the same piece of deployable cover as you, even if you are at opposite ends of the structure.

Tall Cover
Your deployable cover now counts as 3/4 Cover, and the Hit Points increase to 150.

Iron Commander
You gain a special Reaction that you can use once on every character's turn asides from your own to a total maximum of 6 Special Reactions per round. This Reaction can only be used to make Opportunity Attacks, and you cannot utilize it on the same character's turn that you utilize your regular Reaction on.
