Clip1: MG
Clip2: 222
Clip3: Orangepest
There is a real possibility that UKF had gone OP or been balanced BUT the clips are not showing that at all. Let me dissect it:
Lee Enfield moving accuracy from 0.35 to 0.5
Pyrotechnics unlocks 'Off-Map Smoke Barrage'. 25 munitions. Smoke comes from off-map after a 3 second delay; has cooldown is shared amongst all Infantry Sections. Same range as Tommy Artillery Flares.
Target size from 0.9 to 0.85; target size in cover remains the same at 0.8
Lend Lease Regiment Assault Section upgrade removed (see below).
Let's start with the easier one.
Clip3: that would had happen pre patch as well. 2 Grens pushing in the open against IS been on cover still. STATS are equal. The squad which lost model was in the open (single model which was never targeted was behind light) and approach from a shotblocker. The first model that appears get's focused as the squad has no other model to target.
ANY squad of bolt action rifles has less than 50% of their DPS on the move.
Combine RNG for perfect spread of dmg after the first IS model lost and you have the video. 3 models at low HP vs focus fire 3 models down on Grens.
Clip2: not sure what the 222 is supposed to accomplish. The unit was never great against more than 1 squad. Wouldn't a double MG42 + FHT been a better option without any snares nor mines.
Clip1:
All numbers from the top of my head without checking so they can be wrong.
7-8 IS (4 on left. 3 + 1 on right), all at full health, with bolster, nades and at 5 man. That's a 64 popcap army. On top of using assault (or whatever it is called).
As for cost, let's not count the upgrades. Just the squad value + 1 reinforce per model.
(270 + 28) * 8 = 2384
If only 270 * 8 = 2160
If bolster after 4 IS = 2272
3 Grens, 2 MG42. No upgrades (both LMG42 upgrade when the fight is over and would be worst at that distance anyway). Right Gren is a lower than half health. Pak is irrelevant as it not even drawing fire.
So 3 x 7 + 2 * 6 = 33 pop
Cost: 720 + 520 = 1240mp
Let's dissect the 2 fights separately.
Right side trades more effectively cause the MG is on green cover (not just the crew) and all squads comes from a single position been able to suppress them and pin one. But then decides to move it (mistake) cause he fear the nade, which he should just tank it if they were able to be in range (which they don't cause the closest one was pinned).
Incoming 4th IS + suppressed one deal with the low HP gren. Left side IS recovers from suppression cause it barely got suppressed (it was further from the one who was targeted) and was not been fired upon.
Left IS nades the MG (which is now not in cover, 3 models and not firing)
Surprisingly that was a winnable fight or at least trading effectively if he didn't do anything at all besides retreating once the 4th IS appeared.
Left side: the 4 IS against the MG and 2 Grens full HP. Unfortunately the MG model is not in cover (it doesn't matter cause the grenade seems to come from the side).
2 IS comes from far right and 2 on left/middle left. 3 Squads get suppressed but the left one from barely outside cover nades and wipes the MG.
IS which was on the right but more left recover from suppression cause it was not the main squad been shot at and in cover. Most left squad recover cause it barely got splashed by AoE suppression.
