Fun fact: Area of Effect suppression does not have cover in it's modifier. If a squad is standing out in the open next to a squad in green cover, you should always fire at the squad in the open. The squad in green cover will get suppressed too, even though it would normally not be suppressed if directly fired at by the HMG.
Fun fact 2: HMG have very high accuracy against vehicles due to their size. This means that their AoE supression, which is tied to landing hits, is extremely high when shooting at vehicles. Aim at a vehicle next to a squad, and the squad will get suppressed rapidly despite not being shot at directly by the HMG.
