Providing respirators for troops would be hard
They have to be provided by the factories across the hiveworld,factories that we know are not up to date in their IPES (individual protection equipments) or safety measures
So whatever factories are making the fabricator components is probably on a cloud of spores,their workers compromised
The PDF just operate side by side with the inquisitor teams wich clould very easily be a few hundreds guardsmen under a few dozens admech techpriests
Wounds on open air,respirators damaged or knocked off by combat,spores catching on clothes
So we have to go by the asumptions
>the goods and services that interact with the guardsmen are compromised
>the bulk of industy in the hive is also compromised
>the pdf and their officers (and with pretty much all sections of the hive) are compromised
>tide now has knowledge roughly on par with lower levels of the admech,but massively better polished and efficient

On the "use explosives to sink the hive" from the outside
A hive is probably the size of luxemburg with height of the everest
The beirut port explosion was 2.7 kilotons, the biggest nuke used was 50 megatons
That means you need around 18k to 19k ports with their warehouses filled to the brim with explosives,somehow transport all that and set it up and detonate simultaneously
You would need around 20k of those to match a tzar bomb, thats around 49.5 million tons of material
Thats 4k to 5k trains filled to the brim (the US has 23k trains as reference)
And then you gotta put that into shells and fire them
Airforce alone would disrupt such operation without need of tide intervention,and even without airforce voidshields still a thing
You are massively overstimating how much damage traditional explosives can cause and how much you would need
I would reccomend instead for the genestealers trying to hijack stuff like lowyield nukes for the bombardment,there is nuclear artillery shells around the 2.5 kiloton yield and rockets with nuclear low yield warheads
At 50kg the shell,thats around a million kgs
Or a thousand tons worth of shells
Thats more than enough to carry in 20-ish train wagoons on a single train
Massively more feasible than "our zerg rush with improvosed explosives didnt work,lets pull years worth of stockpile of trafitional explosives out our asses,move it around,and barrage the hive for days,weeks or even months nonstop and hope for the best" (tho that could be a plan from the broodmind that has already lost and is grasping at straws)
The question is how to reach whatever silos has such weaponry
Intercepting military personeel,subvert them and use the info to target higher rankong officers?
Rinse and repeat untill you subvert someone that has useful info and then target the silos and key personeel for subversion?
