If they had received timely medical treatment after being shot, there wouldn't have been such a problem considering their physical fitness.
Elijah knew that Lincoln was now out of life-threatening danger, so he stopped and said to Sean Knight:
"Boss, we have achieved our goal this time, but there have been accidents."
It turns out that as soon as Elijah and his two comrades infiltrated Chris's country, they began reconnaissance work.
Following the addresses provided by Loachie, they observed one by one and found that Chris didn't live in any of those three places but rather in an inconspicuous villa.
After confirming Chris' location, the three made a combat plan, with Elijah and Douglas Cooper entering the villa to take action, while Lincoln provided support from a high point outside.
Elijah and Douglas' actions went very smoothly. They entered the villa, killed the guards, found Chris, and completed the mission.
