Sure. Let's say it knows there is something happening with the door, but has not seen you guys yet.
CESN says:
... I'll take the bullet ...
Bullets. It is now thing you have in your inventory till the fiction says it runs out.

... with the camouflage on. D. would think this can buy him a few seconds ...
That sounds a bit like more than just 'fiction'. If you want it to keep you invisible for long enough to do things it really should require a Push. But that seems mean here.
While not setting a precedent for the future, let's say it buys you just enough time to act. How much will depend on the roll.

Fortune:
Critical: Exceptional result / Great, extreme effect.
• 6: Good result / Standard, full effect.
• 4/5: Mixed result / Limited, partial effect.
• 1-3: Bad result / Poor, little effect.
• So a Crit would make you more Effective and lower its Threat.
• A 6 would increase your Effect.
• 4-5 would increase your Effect but also increase the Threat (sorta the same as if you choose to shift both up).
• 1-3 is bad and it sees you before you can act, increasing the Threat.
All of these can be on top of --and separate from-- your choice to shift the Effect and Threat in either direction.
You can describe and roll that, then describe and roll the shot based on the outcome.

Mobility, I would assume?
Possibly you want to add your Glitchy Chemoregulator (if I understand its function) to help keep your heartrate and temperature under control? That will double your dice, but is a risk.
Someone may be able to Assist you in this action?
