Ok quick question can a missile bot use the ap explosive for guided then gain the template effect from guided or is it forced to use its template version? Troopers with the BS Attack (Guided) Skill listed on their Unit Profile: During the Active Turn, they may perform a BS Attack against a target in Targeted State, without requiring LoF. They will perform a BS Roll with a +6 MOD, ignoring all other MODs except those imposed by ECM or TinBots to Guided Attacks. (See FAQs & Errata. Cannot be combined with Speculative Attack.) Unless the Skill itself indicates otherwise, the B will always be 1 regardless of the actual B value of the Weapon or any MODs applied to the B. This BS Attack always applies the Impact Template (Circular) Trait, even if the weapon used does not have the Trait. The distance to the target cannot exceed the weapon's maximum Range. The target cannot be in an enclosed room, a possible trajectory for the Attack must always exist. BS Attack (Guided) has a limit of 5 Attacks per Turn for the Active Player. Only weapons that use the BS Attribute may be used with the BS Attack (Guided) Skill.
It does not mean that if you have the option you must use the Impact template (circular) it means that whatever option you use it will have this trait.
"ignoring all other MODs except those imposed by ECM or TinBots" is pretty clear. Why do you have this kind of doubts? Do you have access to the Rules Wiki?
I guess because it’s not its own BS attack skill like speculative or intuitive. If it was then I’d be more confident that there isn’t some text somewhere else that adds to or provides an exception. I was surprised to find that guided BS attacks rules are tacked onto the end of the bs attack skill section. thanks for the clarification tho!
