Squad refuses to throw AT weapons

[McIvan]

You're just really unlucky, I'm afraid. Usually squads throw those magnetic mines reasonably smartly. But, like you, I've had squads sit and look dully-eyed at perfect targets for turn.....after turn......after mind-wrenching turn....

You might be onto something with the house tho....they will throw from houses, but maybe you were too far back inside the house for a throw that would arc through the air, rather than fire reasonably flat like a faust.
