The report on the future of the Defence Forces presents a political challenge.

Is there an appetite to increase spending in an area that, to pardon the pun, often exists below the radar in Leinster House?

Such a pledge would not be confined to a one-off investment, but instead would form part of annual budgets.

That means defence actively vying with health and housing for more money each October. All precedents since the foundation of the State suggest it is the latter two areas that will win out in such a scenario.

Interestingly, while there is rarely any debate around military spending, there has been ongoing concern expressed in the Dáil about pay and conditions in the Defence Forces.

On this, the commission found there are several anomalies in the remuneration of personnel in the first three years of service.

And it is in these years that higher rates of people leave the Defence Forces.

There is also a recommendation to have an ongoing review of the pay rates of specialist personnel.

Significantly, the commission believes the Defence Forces' representatives should be "active participants" in national pay talks and should be able to join ICTU.

These personnel issues look relatively straightforward to solve politically, but other recommendations may prove more contentious.

The commission found that simply maintaining current capabilities would leave the Defence Forces unable to conduct a meaningful defence of the State.

Then there is there the option to boost spending by €500 million every year.

This would allow for the purchase of primary radar, coastal radar, and military aircraft.

It would also strengthen military intelligence and cyber defence capabilities.

The third option could see the total Defence budget rise to around €3 billion annually.

Everything from "a sqaudron of combat aircraft" to a fleet of 12 naval ships, supported by appropriate technology, could be purchased with this type of investment.

However, that is unlikely to get widespread political backing.

The general feeling politically is that today's report will spark a debate that ultimately leads to a better equipped Defence Force.

But it is likely the level of increased investment will fall well short of billions of euro.

It is probable that it will land somewhere in the region of €100 million extra funding annually.

It will take many months of debate to nail down that exact figure.
