One possible situation is that they have an AFV behind the roadblock, waiting to cross, but the rest of the turn revealed an AT gun on the other side, and removing the roadblock would make the AFV lose HD status. So, cover.I'm trying to imagine what situation prompts your unit to choose not to clear the roadblock after spending the entire turn using Hazardous Movement and under TI...cover?
Actually it was my roadblock and my opponent was trying to clear it...I'm trying to imagine what situation prompts your unit to choose not to clear the roadblock after spending the entire turn using Hazardous Movement and under TI...
Anyway...it definitely doesn't say you HAVE to make the Clearance DR...so agreed it is optional.One possible situation is that they have an AFV behind the roadblock, waiting to cross, but the rest of the turn revealed an AT gun on the other side, and removing the roadblock would make the AFV lose HD status.
Regardless, the RB appears to say that the Clearance DR is optional (though surely it is conditional):
B24.76 ROADBLOCK: Unpinned, Good Order Infantry MMC/Dozer which has not moved or fired (or directed fire) during that Player Turn (as evidenced by placement of a TI counter and the declaration of their removal attempt during their MPh/DFPh) in a Location containing a roadblock hexside may remove that roadblock as Hazardous Movement with a successful Clearance DR at the end of the CCPh (see also 29.5).
