People tend to understand this as only Emniyet will get equipment from TSK while the law says that in urgent situations every service can borrow equipment from each other with the MIT's approval and the signatures of the forces in question (Interior and Defence Ministers).
For example TSK can borrow an Akinci to MIT for a large scale operation with the signatures of MIT's man in power and the Defence Minister.
Another example: Gendarmerie is low on engineering vehicles because they are already working in an internal counter-terrorism operation so it can't assist Emniyet properly but Emniyet needs them urgently. At the same time TSKs engineers in the country are low on numbers because of large scale multi axis cross-border operation but there is reserve equipment present so Emniyet can ask TSK to borrow them engineering vehicles without compromising security.
Another example: TSK is low on TOMA vehicles because there is protests all over Northern Syria and Northern Iraq. Gendarmerie is assisting but it is not enough. In that case Emniyet can borrow TOMA vehicles to TSK for a certain period of time so the public unrest can be controlled.
Another example: MIT is required to do an urgent helicopter rescue of field agents deep in Iraq but because of the nature of the operation, possible security breaches and equipment requirements MIT decides to request for a Blackhawk
helicopter undergone Yarasa modernization but OKK opposes so the Defence Minister opposes and instead TSK borrows MIT a Cougar.
Another example: There is a big unrest in the whole country together with terrorism. Emniyet gave many casualties and they are low on armored vehicles so the Minister of Interior asks the Minister of Defence to borrow an amount of Vuran and Kirpi vehicles to EGM because they can't continue operations safely while at the same time they are giving their purchase for additional MRAPs to BMC and the ones borrowed from TSK are serving as stop gap.
There are many such possible examples and this is not exclusively a bad thing.
I wound advice everybody to look at the document I will post below. This is a document themed on "The Most Dangerous Possible Scenario" for Turkey and it is part of the 2003 1st Army Plan Seminar. I would like to note that the most of the dangers in that seminar are still relevant and very minor details are outdated.
Imagine such a scenario and look around at our geopolitical dynamics and recent threats to global and regional stability.
The threats that TSK thinks are possible to emerge at the same time and pose a great danger to Turkey are as following:
Leftist terrorism (TIKKO), American operation against the Iraqi Government, Shia independent State in Iraq, KRG independence, PKK activating itself in the Southeast, Turkmens in Iraq in great danger demand support from TSK, Cyprus integration, Aegean Sea dispute and war with Greece, Islamist pro-Shariah terrorism and rebellion triggered by the tension with Christian powers.
Document:
“The main thing is the Inner Front. This front is the one concerning the whole country, the whole nation. Exterior front is the direct armed front of the army against the enemy. This front can shake, it can change, it can be defeated, it can be recaptured, but this situation is not enough to destroy a country, a nation. The important front is the one that can destroy a country with its foundations, enslave its nation if its destroyed and that is the Inner Front. The enemies who know this truth even better than we do, worked for hundreds of years to make that front fall and they are still working.
