Who shots first

[McIvan]

There's no formula for picking on vulnerable units that I know of. However.....I'm out of practice with this game, but my recollection is that if you group a HT platoon with a tank platoon, the HT platoon often seems to take the op fire rather than the tank......often enough to leave a vague impression anyway.

However, I am a bit wary of my memory on this point....it could just be that I recall the HTs because HT's tend to die in droves to AP whereas the tanks more often shrug it off.

So I cannot offer any firm conclusion.
