Yes, 1.25 modifier from infantry flamers.
And on the long range, PGs will lose anyway.
Short range however its pure RNG, whoever will better focus and snipe models will win with PGs advantage as they have ~100% higher DPS on close range(on per squad basis).
1.25 modifier, Aoe on a clump up squad, totally ignoring receive accuracy ( its normal, but its totaly nullify the less entity per squad but less receive accuracy OST thing )
NB: as you all see i hate flamers as it nullify so much mechanics on COH2, its ok on engy cause they are fragile, in rifles it was a bad idea, now that penal are buffed, flamer on them is strange
