Wiki is quite bullshit about the cons of Grille. Lets see:
- Below average hit points: Grille 240, M7 240, SU-5 230
So average.
- Below average engine power and traverse speed: Grille 200hp at around 11t, M7 460hp at around 23t, SU-5 130hp at around 10.5t and traverse speed are: 22/20/30
Average traverse = 24deg/s. Grille = 22. Engine/weight ratio: Grille 18hp/t, M7 20 hp/t, SU5 13 hp/t. Avg: 17 hp/t
- Below average armor: Grille 15/15/10, M7 12.7/12.7/12.7, SU-5 7/15/13
Grille wins. Of course, since arty is usually one of the lowest tiers in a game, every shot will penetrate all of those values regardless. Also, SU front armor is weaker than side AND rear?
- Below average damage and rate of fire: Grille top gun 680dmgx3.5rpm=2380dpm, M7 top gun 410dmgx6.48rpm=2656.8dpm, SU-5 top gun 330dmgx6.56rpm=2164.8dpm
Average: 2400
- Below average ammo capacity: Grille 18, M7 69, SU-5 14
Average: 33.6
- Below average signal range: Grille 710, M7 745, SU-5 615
Average: 690
I skiped the below average accuracy, aim time, gun traverse and gun arc but you can check them
I probably should, since those are the factors that determine if you actually hit anything. That is, the most goddamn important stats for arty after damage/shell. Especially when the Grille DPM comes from high damage and long reload time, so missing/time repnt acquiring a target hurts its DPM more than its USA/USSR counterparts.
Accuracy: Grille: 0.55m M7: 0.56m SU-5: 0.49m Average: 0.53m
Aim time: Grille: 5.14s M7: 5.15s SU-5: 4.57s Average: 4.95s
Gun traverse speed: Grille: 17mm M7: 18mm SU-5: 18mm Average: 17,67mm
Gun arc: Grille: +/-5deg M7: +/-23deg SU-5: +/-10deg Average: +/-12.7deg
I'm not saying its super awesome, but it is definitly not below average compared to other tier IV artys.
From the above it is:
Average hp - ok decent. May mean the difference between neededin 2 or 3 shots to kill in some circumstances
Below average turning speed - important when finding a target
Above average cruising speed - but arty is mostly static
Above average armor, but every tank that spots it is likely to penetrate any tier IV arty regardless of where it shoots.
Below average DPM. Way, way below average reloading time. Way above average damage per shot
assuming you hit.
Below average ammo capacity.
Slightly above average signal range.
Below average accuracy.
Below average aim time.
Below average gun traverse speed.
Way, way below average gun arc.
From this we can decide that:
1) The grille is slightly more durable than its counterparts. This will in a best case scenario let it survive 1 shot more if spotted, 2 shots in extreme scenarios. But it will most likely get one-shotted by anything tier 5 or above if seen. It also has the largest profile of the 3 artillery pieces so it is easiest to hit.
2) If shooting at a completely static target for the entire match, the grille will do slightly more damage than a SU-5 but somewhat less than a M7. (Actually way, way less since the M7 will have tons of ammo left over once the Grill and SU-5 run out)
3) The traverse speeds and aiming speeds means the grille will take far longer to acquire a target - especially because the longer reload time means missing is more costly so you'll want to be absolutely certain. This is critical since smart tankers won't remain visible for long if they can avoid it.
4) The tiny, tiny gun arc is an absolute killer, since it means the Grille has to move its hull far more frequently. This resets the aiming timer to a far larger degree than simply rotating the gun.
In conclusion:
The grille is inferior to its US/USSR counterparts in every category that is relevant for a SPG. It will have a harder time acquiring a target. It will have to take more chances with incomplete aim since it has to aim longer and more frequently. Missing your shots - which is more likely because of aforementioned aiming issues - is twice as costly in damage dealt as for its counterparts. It is unquestionably the worst Tier IV artillery.
[edit]
The M7 and in paticular the SU-5 also fire in higher ballistic arcs than the Grille, meaning they will have an easier time shooting past terrain obstacles.
German tank worse in all aspects? In Soviet WoT?

Ah, I hadn't noticed the difference in frontal armor. That is indeed very, very sweet. I'm tempted to grind for it but worried it will get nerfed once SerB notices that Superior Russian Weaponry cannot penetrate frontal armor using autoaim. He is then likely to "correct" this issue by
fabricating discovering historical evidence that the germans turned to aluminium armor plating instead of steel to combat weight issues. A bit like how he arbitrarily decided that the E-type series should have a (highly combustible) frontal transmission, even though a rear transmission were one of the stated design objectives for the E-series, the hulls used in the E-series had no room for a transmission behind the lower front plate, the surviving blueprints for the design depicting a rear transmission and engine transmissions generally being made entirely out of metal and thus not flammable at all.
