When the patrol registered on 2020s radar, he froze, a number of contingency algorithm's fighting a little war for priority in his CPU. His thermal peripheral vision was good enough to see the squad dive for cover, and he did the same, moving behind a small mound a bit deeper into the forest. This cover should be enough, as his armor and weapons had non-reflective coating and didn't appear much more than a bunch of rocks and mud. 

His movements were slow, gradual, but completely silent. A couple of birds landed on his shoulder to get a better view while he was improving his position. As a last step, he shut down all active sensors, retaining only sight, sound and passive EM.

Mar's plan simulated within the droid's head while he was setting his sights on the figure closest to the hiding squad. The energy blade was saturating his heat vision a little, forcing him to use averaging to pick his target on the humanoid's body. If the enemy had the ability to parry shots, his blaster fire should be the distraction for Mar's shot to be unobstructed. However, at this range, the meatbag did not have enough time to react once the shot was fired - he had to anticipate the direction and block before the trigger was pulled. 

This was why Jedi had so much trouble with droids - there was no killing intent, there were only ballistics. Thus, there was a chance the blaster shot would be the one to hit. This wasn't bad - the gun had enough power to rip limbs off and shoot clean through these trees. There were plenty of options for interesting takedowns in this situation, and it was twice the shame 2020's database did not include specific information about interaction of blaster fire and energy blades. Thus, he decided to get that sword, for testing.
