If you've grown tired of your recruits getting slaughtered, I've unearthed a remedy.
Note: you don't have to use cheats; cheats just facilitate the process.
What you must do is activate the firefighter mission, get to level 2, and there must be a Grove member in the burning car by himself. Spray the car (obviously), wait for him to exit then spray him. Here's where it gets tricky: After spraying him; if he is wielding a gun, exit the firetruck without pressing the mission cancellation button/key (which also ends the mission, but still), and recruit him. He will be invincible, even to explosions unless you caused them, or if he's in a car while it explodes. If he was unarmed or was wielding a melee weapon (such as a knife), however, you must press the mission cancellation button/key after spraying him, then get out and recruit him. Seeing as Grove rarely ever are in burning vehicles, it's best to activate the "gangs & workers" cheat (the one where only Grove, Ballas & Vagos and taxis spawn) to speed up the process.
