full burst, because Effects All other troopers participating in the Coordinated Order have their B reduced to 1, regardless of their weapon. And hacking programs are not weapons used for a generic Hacking Skill, but rather each one is its own individual skills.
Also, if you coordinate CC, the non-spearhead all gets no* Burst at all. So really it is only coordinated BS that gets you half on spearhead and B1 on the assisting troopers. *minor edit for clarity
Note that the usual answer for "What's the B on my hacking during Coordinated Orders" is "No, you can't, unless you have an EVO Hacker in your list." Hacking Programs cannot be used in Coordinated Order unless there is a scenario special rule, or the player has a trooper in the Army List possessing a piece of equipment or Special Skill, which specifies otherwise. and EVO Hacking Device allows the use of Hacking Programs in a Coordinated Order. It is not mandatory for all the Hackers in the Coordinated Order to use the same Hacking Program. On the other hand, Effects In a Coordinated Order, the Spearhead trooper uses half the usual Burst (B) of his weapon, including any bonuses, rounded up. All other troopers participating in the Coordinated Order have their B reduced to 1, regardless of their weapon. In CC, the other models aren't reduced to 0 B, they're not allowed to roll their dice. In Close Combat, only the Spearhead trooper will perform the CC Roll, getting a MOD of +1 to his B and +1 to the PH Attribute for Damage for each friendly trooper participating in the Coordinated Order engaged with the adversary. CC weapons are B1, and halving that doesn't turn them to 0, so it doesn't seem to matter whether that bullet point and the the first one both apply at once. But I'm skeptical of anyone claiming the second bullet point doesn't apply to Hacking programs.
I was assuming the OP actually met the requirment of having the EVO HD, he also needs some hacker(s) to perform Hacking program, to be in his Active Turn, have at least 1 Regular Order to spend in the correct Combat Group, and have a Command Token to use. For completionist sake. Bonus: since you do have an EVO, remember EVO also allow you to spend command token to reroll your hacking attack dice :)
+1 to Solkan's interpretation. Which given a lot of hacking programs are B1 or don't have a B isn't actually an issue.
It is not unusual that an effect bullet directly relates to the precedent effect bullet. Those two bullets seem to go directly hand in hand. But I could see how one would say that "regardless of their weapon" means it also apply to other skills that don't have a weapon. I meant no burst as in no roll, because each Burst = 1 physical dice that you roll. OTOH, effect 1 is half burst for the spearhead only. Which in CC as you said half of 1 is still 1, but it is also said to be half of usual burst including any bonus (which could include MA4 and gangup bonus). That the effect 2 apply to CCW or not, does not have any final impact as even if their Burst were reduced to 1 (but is already at 1 anyway) a later effect overules it saying they don't roll at all. Also the CC example skips effect 1 even though there is a Morat Spearhead which have CCW weapon of some sort. Note that if bullet 2 apply to all skill even those without weapon, bullet 1 should apply to all skills that uses a weapon and should half burst after including any burst modifiers.
