Do summoned monsters get DB/DR?

Damage Bonus/Damage Reduction

I think affect all of them.

Meaning sentinels, vehicles, and turrets.

So, my question is: Since Sentinels get to copy the Damage Bonus and Damage Reduction of their master, does that mean summoned monsters copy their master's DB and DR as well? This might mean a lot in the way I spend my med's point's.
If they don't get their master's DB/DR, should they? Since Engineer's stuff does get benefits from their master's stats, my brain is telling me it would make logical sense to allow the same benefit for med's summons, especially since a would-be monster master has to invest more points than an engineer, due to the monster point/loaded monsters split and the near-required monster intelligence. Or maybe Engineer's sentinels shouldn't get master's stat bonuses if medic's pets don't?
What about summoning charm? Does that work the same way as medic's pets? Also, I've long wondered whether summoning charm monsters get Int. bonuses if summoned by a medic.
Also, I'm assuming medic's summons don't get affected by Advanced DR, is this correct?
Sorry, lots of questions.

I think summoned monsters get the DB/DR benefits of the medic, as the code for the engineer summoning was copied from the monster summoning artifacts. However, I doubt if weapon speed points work.

I haven't checked the summoning charm, you get what you get with that.

I believe the answer to this question is yes.

Yes, pets from MM get benefits from their masters, such as health bonus, DB, DR, regeneration, retaliation (not very sure for this), speed, power jump, but NOT with weapon speed, ultima, ghost... and I am still not sure about enhanced damage reduction works on pets or not...

Normal summon charm works the same way just like a MM charm, except monster would time-out for a certain of time. That means normal charm monster would get all the benefits from the master just like MM charm.

Yes, normal summoning charm monsters get Int. bonuses too if they summoned by a medic. You can just watch them by walking: if you have 0 int for pet, they walk really slow, skaarj's energy blast fires slowly too; when you have lvl 7 int, they walk just like normal monster, fire with a good accuracy and know how to dodge.
