I believe that fingerprint readers can be fooled with either a latex
impression or a dead finger.

Some devices can the cheaper ones. But why are we seucuring the door
from
others is the important thing here, and it;s not like no one has ever
gained access without the correct key to any place, it;s just what
effort
you need to take to eliminate such a thing and in most cases I doubt
many
people carry a dead finger around with them, or have access to the
latex
and a suitable finger.
Face recognicion is another option, I've heard in the USA they are
looking
into guns that can only be fired after face recogniction has been used.

implementing "owner" recognition for gun triggering has been considered
by
military for at least 20 years.

But only recently had the technology become cheap enough and small enough.


It all fails to solve the scenario of what happens if trouper A needs to
"borrow" the gun of (dead/incapacitated) Trooper B in hurry, in a
battlefield scenario

No it doesn't.
It just needs a little thought like dual access bank accounts.
But it does depend on what you mean by in a hurry.

I can se NO reason why a face or finger print must only be for ONE person
/ ONE gun.
You could have everyone in the platoon have their face recorded as ID for
every gun.

Be interesting to see how the best of it handles camo face paint etc. Likely
fine.

My face varys lots, because I havent been silly enough to shave
for decades now and let the beard get quite long before I mow
it back to a stubble with a hair trimmer. Not clear how even the
best of the iphone facial recognition handles that. I'll have to
try sometime because Apple has given up on fingerprint sensors
now, mainly so the full screen is available for the image that
you are viewing. But I only upgrade my iphone when it has
something that I need so unless it gets lost or smashed it
will likely be a while. While in theory I could buy another
of the same as I have, in reality they dont sell the largest
memory versions anymore with the discounts of what I
have. I have a 256GB and would hate to go back to a
32GB now. I mostly use the difference for videos and
automatic podcast updates and the photos of the
garage sale ads in the paper that I might get around
to OCRing so I can search sometime.

At the very least you could have a 4 digit number override, and
everyone in theat platoon get the 4 digit code for the day/week.

Wouldnt like my life to depend on how well that can
be remembered when the **** is hitting the fan tho.

At least 5 of my friends know my 4 digit code
for my ipad which is the same for my TV box.

Sure but that isnt changing weekly and they dont
have to remember that when the **** is hitting the
fan very spectacularly indeed and they will die if
they dont manage to remember it. Much lower
risk of one of the enemy getting close enough
to grab one of your platoon's guns and using it
except with some of the more extreme situations
like in Rhodesia or Mozambique in the past or
Chad today.

I'm betting even harry could design a systenm where
every gun can be operated by anyone with a white skin,
but if someone with a black skin picks it up it won't work.

Trouble is that they wear camo on their faces and with
some conflicts like Rhodesia a substantial number of
the platoon were in fact black even with the white side.
And in fact they had small groups disguised as terrorists
to **** over the real terrorists/'freedom fighters'.

Do you really think it's beyond us to design a gun activation systemn
that can be operated by more than one face or one finger print ?

Corse not but it remains to be seen how well that works
when the **** is hitting the fan very spectacularly indeed.

And with armed cops with the perp grabbing the gun from
the large footed goon and using it on the large footed goon.
