yes, the cromwell is small, it's also one of the the biggest reason the cromwells are viable in a game where the axis anti tank weapon penetration cut through allied armor.
If you want to nerf the cromwell, nerf its rotation rate. Its high rotational rate of 38 is what allow it to crush infantry so easily. From my personal testing, Lowering the cromwell's rotation rate to 32 will its remove itslawn mower capability while still allow it to out maneuver axis tanks.
that smoke ability is also one of the few smoke ability for the british. Yes, a sighted cromwell can smoke the atg with impunity, but that's called combined arms. (comet's WP smoke is another mater). Unless the british get some sort of mobile smoke, the cromwell's smoke need to remain at 80.
Any actual dedicated or semi-dedicated anti-tank will cut through most mediums without question, however. 18 target size is ridiculous, when you consider that's the same size as the larger scout cars. A target size of 20 will still make it the hardest medium tank to hit in the game. Furthermore, the Cromwell sits at a modest cost for what you get in the package. A good gun, fast speed and good mobility, TC upgrade, and very strong offensive veterancy. Having even just the most average target size at 20 isn't going make the Cromwell bad.

Also new quick update that was rushed out. Note there are plenty of issues with the mod as the April 6th patch killed squad_apply_actions:
Additions
OKW
Slight late-game veterancy nerfs to Panzerfusiliers and Obersoldaten to put them more in line with other infantry. More might follow depending on the unit. Vet 4 and 5 should be slight increases, not considerable.
-Obersoldaten Veterancy 4 RA modifier from 0.8 to 0.9.
-Panzerfusilier Veterancy 4 Accuracy modifier from 1.2 to 1.1.
-Luchs Veterancy 5 suppression from 0.5 to 0.09. (Could pin units if two rounds hit)
ISG 75mm
Reduced the auto-fire range to match other indirect-fire weapons. With the recent buffs, the ISG no longer needs such extreme range when on auto-fire/unmicroed.
-Reduced auto-fire range from 100 to 80.
AEF
WC-51
Given the ability to toggle stealth. Four second delay, shuts down weapons, and movement, but makes the WC-51 a unique scouting unit where it can hide from enemies while being relatively cheap as well.
-Given the ability to toggle between a stationary cloak and movement/combat.
British
Universal Carrier
Slight manpower reduction from its cost in the mod to better represent it's efficiency.
-Cost from 260 to 240.
