I need tactical help

[Suhiir]

For my part I'd stay as far as possible from one of our tanks on the advance, as others have said they draw a LOT of fire.
As Griefbringer pointed out there may be some advantage if all the fire is coming from one direction, but these days a 'fragmented battlefield' is the norm. Gone are the days of defensive lines, it's all strongpoint or hedgehog defenses, because that way the loss of no single position means a breach in the defensive belt. Thus you're usually catching fire from at least two (or MANY) directions at the same time.
