The volume of military exports from Poland to Ukraine has been published, it includes not only about supplies from defense enterprises, but also from arms brokers. It helps estimate the volume of arms supplies for the Armed Forces of Ukraine that go through this country.
As Defence24 notes, according to the UN report, 268 units of armored vehicles, 18 155-mm AHS Krab self-propelled tracked gun-howitzer, 78 122-mm 2S1 Gvozdika self-propelled howitzers as well as ten 85-mm D-44M guns were sold to Ukraine. The list includes only sales without taking into account the donated military assistance from Poland.

Of particular notice are the D-44 guns, which were adopted for service back in 1946, but during the russian-Ukrainian war repeatedly appeared in service in various units of the Ukrainian Defense Forces. Although they were in service with Poland, most likely the exported ones were purchased from a local arms broker.
Next come the 2S1 Gvozdika self-propelled howitzers, which were in service not only with the Armed Forces of Ukraine, but also with the Polish Army, from where they were transferred as part of military aid. It is difficult to assess where these specific vehicles on the list come from, but since they are mentioned among the sales, most likely arms dealers are were involved here, too.

Everything is much simpler with the Polish-made AHS Krab self-propelled tracked gun-howitzers, delivered under a contract for 54 units that was signed in 2022. Thus, it can be roughly estimated that the production of these systems is about 18 units per year, given their small number in the Polish army.
As for armored vehicles, this most likely includes a diverse set of materiel. However, it is worth noting that a significant part of the 268 units are Oncilla armored personnel carriers, which are purchased for the needs of the Ukrainian Defense Forces.

On a note from Defense Express, this list is incomplete and will be supplemented when the Ministry of Foreign Affairs of the Republic of Poland publishes a relevant document. Still, it tells enough to assess the scale of arms exports to Ukraine through Poland.
Defense Express adds that Polish companies act not only as direct manufacturers-suppliers, but also as brokers that resell equipment purchased in third countries. Such supplies help to meet the needs of the Ukrainian military in the ongoing russia-Ukraine war.
