I wrote that no mission counts kills. Too strong. What holds is narrower: no mission reads the two GLOBAL counters (33/34, verified 0 sites). The game does track kills and missions test them through attribution: built-in 105 killed_by_player(unit) -- reads [squadron+600], which the unit-death handler sets from the damage message's _BY_PLAYER flag -- 117 sites across 14 stages (S02: 38, S01: 32), the 17th-most-used built-in in Stage 02. built-in 72 -- numerator is a per-(killer, victim) squadron KILL COUNTER, incremented in the unit-death handler; 13 sites, S01 only. So 'did the player get that kill' is a common predicate; the game just never asks 'how many kills in total'. Evidence for 105 is the game's own strings: the death handler branches into KILLED_BY_PLAYER vs KILLED, beside LOST_TURRET_BY_PLAYER, SHIELD_DOWNED_BY_PLAYER and the rest. Also withdraws the 'current / initial members' gloss on built-in 72: it is 100 x (units of B killed by A) / (declared members of B), attributed kills rather than survivors, and reads 0 unless the script registered the (A,B) pair. Built-in 55 resolved and shown to be effectively dead (0 sites corpus-wide); built-in 75 confirmed as five HUD text lines via a [phase+376] dictionary.
