Terms...semantics. Always a problem
"In cover"
We chose this phrase because it portrays better what the game does. Units do not entrench in the game. They can begin the battle entrenched.
"Entrenched" implies that some fancy work has been done on that location.
We did not want to convey that. Beginning the game in an "entrenchment," now THAT is entrenched. What happens during the battle is that units dig in, tanks seek some sort of ground cover, a slight rise, some heavy underbrush to break their silouhette (however you spell it

)
Within the time frame of SPWAW "in cover" is much more accurate and is NOT the same as a unit in an entrenchment.
So please understand by "in cover" that the unit is finding some temporary cover to at least partially protect it from attack.
So what you have is really three types of cover.
Fortifications...Serious protection, but you know that.
Entrenched...Improved positions, maybe some overhead cover, organized defensive position
In Cover...hasty defensive position, scraping out a hole with your helmet or an entrenching tool, hiding in some undergrowth or tall grass, etc.
Those are the only three I can think of. I hope this helps you understand what we mean by "in cover"
