Afraid so, but it can be the two-pointer.
First enemy drops a grenade - which you can pick up when you’ve thrown the other one. Second enemy drops a crowbar.
Enemies move towards the visible Bruno.
Which leaves three dice of enemies (one who was in there already, two newcomers who’ve just arrived from the west) to fire on him from the northern room, needing 4+:
