Very. This might be an outdated mentality but to me these 9-5 soldiers that sit in a base all day are barely any better than internet armchair operators.
To use an expression 'everybody chooses their trade'. Back in the early 2000's the British Army started civllianising certain roles within units that were essentially 9-5. Instead of soldiers that were paid decently, they hired the cheapest civvies they could find, which were usually retired soldiers and eastern european immigrants.
They ran down the employment of Chefs, Clerks, Metalsmiths (this was a real killer for Afghan and Iraq), certain types of store men (don't worry you'll get all your kit that we should be issuing you now, when you arrive in theatre).
It got to the point where Regiments were completely reliant on higher level assets as soon as they left camp. Eg. if a unit wanted to send a platoon to a patrol base, they wouldn't have a chef they could send with them, so they'd have to rely on rat packs.
tl;dr if 9 to 5 soldiers deploy then they're still soldiers and the only lesson you should ever learn from the British Army is how not to do things.
Where do you think the 'RA got their hardware from? Early days by raiding British armouries, then later from sympathisers in the US (including theft from NG armouries) and of course shipments from Colonel Gadaffi because it was an excellent way to fuck with the west.
Fortunately the global arms market hasn't just been flooded with massive quantities of US issue kit from Afghan, and fucking about in other people's local wars by shipping in massive quantities of ordnance including MANPADS, man portable AT kit, artillery etc. hasn't been completely normalised by the Ukrainian fuckery. Certainly the Russins would have no motivation to slip a few conexs of toys over the southern border.
The IRA never raided any British Armouries. Some rifles were stolen, usually by local UDR and handed over to the loyalists.
I wonder what's to stop the Russians gathering up all that captured Ukrainian equipment and shipping it back across the border into Europe. Hey Ulster Loyalists how would you like a few ISO containers of Steyer AUG's. We'll even throw in a few captured AT-4's all with made in the EU stamped on them.
Or just go and find every disgruntled political group they can find and throw captured western weapons systems at them.
The US were smart with the Stinger and the seeker needs a bespoke battery that's impossible to bodge (unless the russians manufacture something for it). All the Danish Stingers that they were going to send to Ukraine were found to be unservicable, because the batteries were dead.
They didn't do the same thing with the Javelin though.... and Ukraine is flooded with them.
