We debated whether this was a straightforward linear programming problem or an easy convex optimisation problem. Given that the former is a subset of the latter, it's actually both, so we felt free to choose the cooler sounding one.

As I mentioned before. Baze is doing the aiming. And he really seems to be using his eyes. High level of camouflage (a.k.a. invisible) would bother him.
The mechanic of +1 to hit for each round of aiming versus the chance of being hit by a tank increasing is a wonderful trade-off mechanic. Unfortunately, this is an old school style of mechanic. The style that says that PCs are likely to fail. This fits perfectly into a story that we are told is a total party kill.
Living dangerously. I bet he gets hit just before he fires next comic.

Transcript
{a heavy armoured tank chases Baze and Chirrut across the sand towards the cover of a small dune}
[SFX]: Pow!
[SFX]: Kaboom!
Chirrut: Baze gets +1 for each round he aims at the cockpit window, but the chance of getting hit first by a tank increases each round.
[SFX]: load {Baze loads a rocket launcher}
GM: So how long does he aim?
Chirrut: It's an easy convex optimisation problem. Let's see. With 75% cover, assuming standard scanners and random targeting...
Chirrut: Seven point four rounds.
GM: So, seven?
[SFX]: aim... {silent beat as Baze aims and Chirrut thinks}
Chirrut: Let's live dangerously. Eight.
