Currently there are card interactions that are unintuitive and inconsistent regarding "when this unit moves into the frontline (...)" triggers.
Let's take 361. Afrika Regiment as an example: It's text says "When this unit moves into the frontline, deal 3 damage to the enemy HQ." When the 361. Afrika Regiment of player A moves into the frontline during player A's turn, player B's HQ takes 3 damage. But if the same unit of player A moves into the frontline during player B's turn, player A's HQ takes 3 damage instead.
=> This shows that "the enemy" for frontline-triggers is **relative **to whose turn it is.
This is inconsistent with how other words are static and don't change depending on whose turn it is; e.g., "friendly units" always denotes the same units, no matter whose turn it is. Or Akita Regiment ("Destruction: Deal 2 damage to a random enemy") dying will always deal 2 damage to the same player, no matter whose turn it is.
I think that words like "friendly unit(s)", "enemy unit(s)" and "enemy" should always mean the same player, and not change depending on whose turn it is. But the way current Frontline-Triggers work goes against this, is unintuitive and inconsistent.
