I've seen alot of discussion over the last few months about the dire state of Ostheer's infantry in comparison to their opponents.
Grens and P-Grens just don't cut it when facing Riflemen, Inf Secs, penals etc. Despite having access to the most robust and well equipped support weapons that they fight alongside, they tend to melt in the face of even light resistance. This is likely due to the fact that the faction hasn't been touched since the release of both the Western factions and the Brits.
One recurring theme has been the call for an elite infantry in their t4, but i don't think it should be a form of hardened veterans like the knight cross holders from vanilla coh, as no one wants to see ober clones for the wehr.
My suggestion would be, and keep in mind this is working within the current resources of the game.
Grenadiers are reworked into a defensive line infantry, they recieve both accuracy and weapon cooldown when in cover like infantry sections do. They remain as a four man squad with adjustments to the poor spacing that cause so many wipes, maybe the addition of a small amount of armour like they had on release, this compensates the fact that they only have four models with eighty health, against the more robust OKW volks, rifles and other mainline infantry who use five or six men per squad.
Weapon Upgrades. They keep their mg42 upgrade, rifle grenade and panzerfaust. But they lose the medkit vet ability to be replaced with an unlock from their loadout. I then would suggest, and here is the idea that will cause much controversy, give them the ability to upgrade with the dual Panzershreks (they would lose the panzerfaust as a snare upon finishing equipping the panzershreks), gaining the vet ability to perhaps lay tellers or detect tanks, against a maybe a light suppresion ability that the mg could provide.
Their design nature then forces them to fight from static cover or they won't have the accuracy or weapon cooldown to be truly effective, this prevents people blobbing them into a reworked volkshrek horde.
Assualt Grenadiers Next I would transfer the P-grens to t3, something I'm sure many will disagree or argue against. Instead T2 would recieve the assualt grenadiers, removing them from the call in from the mechanized commander, ( both the unit and commander sorely needing reworking.)
Reworked Ass-Grens. WIth the appropriate buffs, forming them into a four man squad with mp40, they would have their model 24 and sprint, but their vet1 upgrade could be to neutralise and capture points at something like %50 or %33, vet 2 being weapon accuracy and recieved accuracy, and vet 3 providing a fifth man armed with an stg44, giving them the ability to survive into the late game.
This gives the Ostheer an offensive infantry that is best used to flank and then cap and hold a position while they reorganize their support weapons, eventually transferring into a five man squad that is more robust than the Grens and P-Grens in the late game and giving them a unit that is tough enough to survive the more powerful weapons and abilities of the late game that are used to cover essential vps or munia nd fuel points.
PanzerGrenadiers. And so, Panzergrenadiers are supposed to be the elite troops of the Wehrmacht, they were meant to be the best equipped and trained soldiers of the German army, tasked with spearheading assualts from their vehicles and working closely with the panzers to break enemy lines.
Reworked P-Grens. Therefore moving them to t3 or t4 would allow them to be buffed to a higher level and represent the elite infantry people are calling for, but instead of being another team of Obers and Falls, I would focus on their theme as being mechanized infantry. They could begin armed with Stg44 or perhaps kar98 with the choice to upgrade to 4 stg44's, access to bundle grenades and smoke, with the ability to give vehicles basic repairs, their vet1 could be somehthing like mark target to increase vehicle accuracy against units or perhaps a passive version that allows vehicles to hit targets they are focusing better.
Weapon Upgrades. Finally a weapon upgrade in the form of the Panzerbusche 39 at rifle (the weapon model already exisiting in the campaign), a high damage, high pen at rifle that could unlock the ability to eprhaps stun a tank or prevent turret rotation with a shot similar to the brit sniper. Then it would only require small tweaks in either armor or a fifth model to allow them scale well as the panzer grens already have a great vet system.
Panzergrandiers would be at their best when working alongside a vehicle as they follow the combined arms design Ostheer is based on. Though I am unsure that an increased squad size fits the theme, so how to increase their survivability is up to debate.
Of course i agree that my idea would not be a perfect design that everyone would agree on, and would also require alot of work to create, but it does fit with the axis theme of tiered infantry in comparison to the allies single mainline infatry that are upgraded throughout the game. Each of the 3 mainline infantry have a defined role, and the P-grens would be more fitting in the faction theme of working in tandem with the late game german armor.
