No, because when the unit is targeted by ranged attacks, they count as Characters and not as rank-and-file models (see the last paragraph on page 81).

So far we have described units consisting of idential rank-and-file troops. However,  more often than not, warriors march to war under the leadership of a captain or some other officer, to the accompaniment of a drum or horn and beneath the fluttering standards of their cities and rulers. The regiments of the Empire march under flags bearing the coats of arms of their Electors and their Emperor. Bretonnians go to war bearing the glittering heraldic banners of their dukes and king. Orcs wave ragged banners covered in glyphs proclaiming the might and power of their chieftains. Standards and drums also have a practical value: they are used to signal to the troops, direct their unit's movement and provide a highly visible point around which formation changes and manoeuvres can be made. The rules that follow represent the boost that the unit's 'command group' (its champion, standard bearer and musician) give to their comrades' fighting prowess. Remember that even if they have special rules, they are otherwise rank-and-file troopers in all respects.

You must break it and pursue, in the same way as for capturing their banner.
