BattleTech Alpha Strike FLK-Guide: Air Defense & Flak Rules Explained<\/strong><\/h2>\n\n

In today’s blog post, we will be looking at one of the most important special abilities for securing airspace: FLK (Flak)<\/strong>.<\/p>\n\n

Anyone who’s ever been orbited by a fast VTOL or been hit by a low-flying aerospace fighter knows how difficult these targets are to hit. The flak rules<\/strong> in BattleTech Alpha Strike are designed to effectively neutralize these nimble threats. I will now explain how this works in detail. <\/p>\n\n

The core rule: damage despite a miss<\/h3>\n\n

The FLK#\/#\/#\/#<\/strong> (Flak) special ability is a lifesaver when the dice don’t quite roll. If my unit declares an attack against an airborne target (Airborne)<\/strong> and only just misses<\/strong> the hit roll – specifically by a Margin of Failure (MoF) of 2 or less<\/strong> – it still scores a partial success. <\/p>\n\n

In this case, the unit causes damage equal to its FLK value<\/strong> for the corresponding range class. So if I fire at an aerospace fighter at medium range and miss my hit roll by 1, but have an FLK value of 2, the opponent still suffers 2 points of damage. <\/p>\n\n

What is a valid target for FLK?<\/h3>\n\n

The flak rule does not apply against normal ground units. I can only use it against: <\/p>\n\n
