Is it just me?

Now that you mention it, are we talking about the CAMO game or WaW/H2H?

For the CAMO games: units lose one of their ROF as soon as they get 5 points of suppression. The amount of suppression needed for another ROF to be lost depends on exp/mor. For low quality troops the point of either no shots or retreat status can even be under 20 suppression.
When taking casualties squads don't just take suppression too (which can jump to 99 instantly when taking a loss) but lose shots from their MAX ROF for the second, third and fourth weapon slot.

Few squads can take 3 volley's of mmg/hmg fire in clear terrain at less than 500m without getting pinned. Rallying can remedy that off course.
